How easy is it to replace upper control arms?

Is it as simple as jacking up the jeep, removing the wheels, three bolts, and replacing the UCA?

Anything else or other advice I should know before attempting this? I know I'll need an alignment afterwards.

Thanks guys

Re: How easy is it to replace upper control arms?

You've got to separate the ball joint stud from the spindle. Whack on the flat spot with a hammer or use a Pitman arm puller. Leave the nut on with a few threads engaged to keep the spindle from flopping loose.

Re: How easy is it to replace upper control arms?

The arms I bought have a ball joint already, do I still have to do that?

Yes. You still have to separate the UCA from the knuckle. It's not a bad job, but you sometimes have to play around with the position of the lower control arm to get everything out. Also, it can be a little tricky to get the bolts back in after they are removed. Certainly manageable for the diy'er

Re: How easy is it to replace upper control arms?

It's not difficult to remove but it does take a bit of work to get all the bolts loose and out. I had to loosen my strut tower to get enough play to get the bolts out.

Re: How easy is it to replace upper control arms?

I just did this last weekend when I replaced my struts. It's not that bad. Loosen up the strut tower(18mm), take off the ball joint nut (18mm), a couple of pounds with the hammer will separate the ball joint from the spindle arm. The bolt head inside the wheel well is 15mm, the nut in the engine bay is 18mm. If you have a plastic rivet gun take out the wheel well cover as it will make it easier to get at the nuts, but not required. I would plan ~3 hrs to be on the safe side.

I looks easy but I had the shop who installed my front strut replace my upper arms I paid about 200 for the arm install I am sure I paid to much but I had they where cheap on the strut install. Just shop around do not go to dealership.

Re: How easy is it to replace upper control arms?

Apparently its more difficult if you have a lifted jeep with a 2" spacer lift as everything is generally under higher tension, so you may need to use a spring clamp. I didn't actually perform the change myself, my friends at the garage did this when I swapped the stock ones for the JBA ones for lifted jeeps, amazing product btw.

Re: How easy is it to replace upper control arms?

I'm going to be doing this in the next couple of weeks. Ordered Moog UCA's with ball joints, Moog front end links, and Moog, Tie Rod Ends, all of which are OEM and I've got about 120k on the clock.

The combination of replacing those parts should give me a lot less play in my steering!

As a FYI, there's a great pictoral write-up on the red site of how to do this, including tools needed and removal/installation of the plastic fender trim too!

Nope, I just bought a set of outers. I've never replaced the inner set on any vehicle, so I didn't grab them this time either. If the combination of these 3 part replacement on each side doesn't work to stiffen up with loose steering, I'll look further into the rack at that time.
