Rocky Road Outifitters 2.5" Coil Spacer Lift Install

So I promised a write up and some pics on the install so here it goes.

NOTE:
I am not trying to replace the directions provided by Rocky Road; this is just a recap of my experience.

CAUTION: If you are not mechanically inclined I would suggest that you have a shop perform this installation. While the lift itself is not hard the complications that can arise when installing the front may prove to be too difficult for some. RROs instructions assume a bit too much, IMO. The instructions indicate 1-person could perform the lift. I disagree. There are many occasions in which and an extra set of hands are certainly necessary.

My buddy and I performed the installation in my driveway over the course of two evenings, about 9-hours total. He was a Chrysler mechanic for nearly 8-years so he has a lot of specialized tools. And, he and I have been working on cars and lifting Jeeps since we were 13 so 1) we are pretty knowledgeable and 2) we have a good working chemistry. We usually know what the other is thinking which helps when things aren't going as planned - which always happens.

All right now on to the good stuff.

The Instructions suggest starting in the rear. I concur. No surprises when installing the back I don’t think I took any pics of the rear install – sorry.


Rear
Pretty simple, jack one side of the vehicle, properly support (don’t forget to chock the wheels), remove the wheel (if using hand tools break lugs prior to jacking).

The RRO instructions don’t mention anything about the felt liner. Well, it needs to be moved out of the way. Simply remove three of the retaining clips with a small flat head screwdriver and pull the liner inside out. Don’t worry; it will retain its shape when it goes back after the install.
Then remove brake line clip and sensor. Then remove the lower shock mount bolt, upper control arm bolts and disconnect one end of the sway link. This is why if you plan to install BWoody links it is beneficial to do it now.

With the bolts removed stand on the lower control arm and have your buddy pull the spring out. Next, remove the shock and install the spacer with the new hardware. Then, install the new spring spacer atop the LCA, retaining the factory rubber isolator with the new bolts. Don’t forget the huge washer underneath the LCA (I almost did). You will need to have your buddy once again stand on the LCA to create as much space as possible to for the spring to go in. Using your jack to help support the weight and compress the spring you can more easily re-install all the bolts.

Now, be sure to triple check EVERYTHING you touched and go to the next side.


Front
The front is definitely not as easy as the rear. The RRO instructions say it will be more challenging – they weren’t kidding!

Start with supporting the vehicle, etc. Follow the instructions and the recommended bolt removal and re-installation order – works great.

Be extremely careful removing the coil & strut, you do not want to damage the CV boot.

The picture in RROs instructions show the axle hanging freely and it mentions that it MAY fall out and it is not a problem. While it is true it is not a problem it is not true that it can be “tapped” back into position – at least very easily; it is a bit more complicated than that. The axle it what gave us the difficulties.


Getting the axle back in
This is probably the most important information that I can offer.

You will need to have the strut attached to the LCA and the LCA reconnected to make this work.

Getting these two bolts in is very difficult – keep them nearby for you may have a short window of opportunity when all the holes are lined up.

We connected the strut first using a jack, two pry bars and our feet. The strut should be held loosely in place up top. Once we got the bolt in we quickly hand threaded the nut.

The LCA mount was just as difficult; two pry bars, two feet, two hands and a jack.

The, Sway Bar, Tie-Rod and Knuckle (UCA) bolts can remain disconnected.

The axle use a Tripod Joint.

Tripod Joint:
These joints are used at the inboard end of car driveshafts. This joint has a three-pointed yoke attached to the shaft, which has barrel-shaped roller bearings on the ends. These fit into a cup with three matching grooves, attached to the differential. Since there is only significant movement in one axis, this simple arrangement works well. These also allow an axial 'plunge' movement of the shaft, so that engine rocking and other effects do not preload the bearings. A typical Tripod joint has up to 50 mm of plunge travel, and 26 degrees of angular articulation.
*Source - Wikipedia.









With the spacer in you will not be able to get the axle level with the differential housing; it is just not possible due to the limitations imposed by the strut fork. If you are somehow able to get the axle level then yes, the axle should tap right back into place. Seeing as we couldn’t get the axle level we had to explore many different options.

We were finally able to get the axle back in by positioning the yoke in a “Mercedes-Benz Symbol” orientation (1-pt at 12-O’clock, 1-pt at 4-O’clock and the other at 8-O’clock). We removed the retainer rings carefully – see picture, so we could see what we were doing. The last thing you want to do is break the CV boot.

Then grabbing the two lower points of the yoke we squeezed the end closest to us upwards helping to level them out. We also had to push the front end (end nearest the differential) of the top point downwards to help level the yoke out in order for it to slide back in.

We then pushed on the axle (used our bodies against the disc brake and knuckle – which BTW is extremely heavy and considering the height at which you are working there is not much leverage to take advantage of) with constant force and the axle popped back into place.

After we popped it into place we carefully and quickly installed the knuckle bolt (we had it and the nut in VERY close reach) so it would stay in position. The sway bar and tie rod followed.

Again, nearly 2 hours to install the rear, but the second side only took like 30-min once we knew what we were doing. The front passenger side took about 4-hours and the front driver’s side was just under 3-hours. So we learned a bit and improved. If I did it again I am sure it would go a bit faster. If going to a shop I would expect to be billed 6-hours at a shop; maybe 4-hours if it is an off-road performance shop and they are use to this.


So, that is basically it. Notice the lift helps to level the Jeep out and provides much greater height in the front over stock. BTW, I measured this in the road, which is flat, not my driveway.

I plan to get 275/60r20 (32.99" x 10.83") Yokohama Geolander ATS tires on the Overland 20s. RRO installed a 275/55r20 (31.91" x 10.83) but a lot of members have that tire on their stock Wk2s. RRO says you can go taller with minor fender trimming - I don't see the need for that. However, I don't think you can go any wider that a 10.83" tire without a wheel spacer. I may even need a small wheel spacer to run a 10.83" tire - there is not much room inside that wheel well.

I apologize for the lack of detailed photos. I’d be happy to answer any questions for anyone. Still haven’t driven it yet; going to get an alignment tomorrow morning.

Hopefully the install goes better for you with these tips.

Awesome. how's the ride? increased body roll? did you install the Bwoody sway links? or does the lift kit come with new ones? looks sweet, i'm jealous!

Maiden Voyage was a few minutes ago to get an alignment, very scary 2-mile drive. Aside from my wheel traveling every which way I made it safely and am now waiting, let's hope for no issues.

No real comment on ride quality yet but from the short, terrifying trip it seemed very stable and I had to go through three turn-circles. It did feel great to sit up higher.

No, I didn't install the BWoody links and the kit doesnt come with them; just front and rear coil spacers and rear shock spacers.

Fortunately, BWoody's shop is 4-miles from me so I'm gonna drop in next week and see if he is interested in making either longer sway links or qwik-disconnect links. I still have the plans for the custom qwik-disconnect links I designed for my ZJ that had a 9" lift - they may be an easy modify.

Re: Rocky Road Outifitters 2.5" Lift Install

UPDATE:
So, I have only driven a few miles but so far it rides great. I am sure it will be much better when I get some wider tires and some taller tires with more sidewall.

It feels great to sit up high and I didnt really notice any body roll. Granted, I am not taking turns at 40-mph.

INSTALL NOTE:
If you HAVE to remove the CV Boots be sure to buy the clamps, grease and clamp tool before putting the lfit on. I called the dealership after the install and found you can only buy the factory clips if you buy a whole new assembly.

I bought large, universal ear style CV boot clamps ($1.09/ea), two packets of axle grease ($3.09/ea) and a CV Boot Clamp Tool ($8.99) from NAPA. Very easy to install. Just be sure to properly clean the boot and wear disposable gloves. The grease stains worse then printer ink so you will not get it off your skin, cuticals or clothes very easily. Do not use hose style clamps as the tab slots will eventually wear down the rubber boot, its needs to be flat and smooth. Also, the screw will unevenly distribute weight around the axle. Zip ties will work in a pinch but are not a long term solution as they will deteriorate from the hot/cold weather and engine heat.


I'l keep everyone updated as I drive it more and also when I get the new rims & wheels.

Re: Rocky Road Outifitters 2.5" Lift Install

UPDATE
I finally stopped in to see Mike at BWoody yesterday (Wed, 13 July) and he is going to make me a set of longer Sway bar links for 2.5" Lifted WK2s - he took some measurements.

Looking at the front sway bar he agreed that it is certainly necessary to lengthen the links, which is the reason I dropped in.

I pick them up on Friday (15 July). I am sure he will be selling them as well.

No news on rims/tires yet. My rims arrived damaged so I am waiting on USPS to finish the insurance claim I filed. For those curious here is what I wrote up on the tire selection :33s and the 2.5" Rocky Road Spacer Lift.

Re: Rocky Road Outifitters 2.5" Lift Install

Thanks for posting the writeup.

"The picture in RROs instructions show the axle hanging freely and it mentions that it MAY fall out and it is not a problem. While it is true it is not a problem it is not true that it can be “tapped” back into position – at least very easily; it is a bit more complicated than that. The axle it what gave us the difficulties."

Do you think it would be worth using a quality spring compressor to remove that coild assembly vs allowing full droop of the axle to get it out? Not sure it is possible to get in there to do so, but popped into my head trying think of waus to prevent that axle from coming out. It seems that was the part giving all the trouble?

1 more Q: i saw that you are going with the factory wheels, but may have to use spacers. While not a huge issue if a quality spacer is used (I have used spacers in teh past) I am also looking into different wheel/ tire packages. I'm guessing you'll be bale to share more once your wheels get straightened out, but what offset is needed to run the max tire size in there?

Thanks in advance!
Tim.

Re: Rocky Road Outifitters 2.5" Lift Install

Timgco,
If you have a spring compressor that would fit it would most certainly solve the problem. You wouldn't have to compress it much either. The guys running the 1.75" Tuff Country level kit aren't reporting this as a problem. My question is why RRO warns that they axle may drop out but doesn't suggest a spring compressor as a required tool... so I am not sure how small they are.

If you have the means you could always make a metal bar clamp using nuts & bolts to compress the spring.

Regrading the wheels, check out this thread I wrote: 33s and the 2.5" Rocky Road Spacer Lift

Bottom line, I think a 33" x 10.83" tire will fit without spacers so long as the measurments are as close to that number as possible. However, there could be some rubbing when going around sharp turns or small traffic circles (round-abouts) to fast or off-roading at a fast speed.

If you can increase your backspacing by even 0.25" then the 33" x 10.83" tire should be no problem.

As far as other tire sizes are concerned... it all changes so much as they are ratio driven so I didnt investigate much further.
