Re: Wk2 Rear Knocking Noise Aussie GC Laredo

I just got word today of the status of the national backorder on the shock and shock mounts ending in AF version to replace the AD in the TSB.
The backorder now is 38,000 units in national b/o. They still don't have a date for when they are going to be release to dealers to start making the exchange under warranty.
In Puerto Rico where I live there is 5 cases filed to the Better Business Bureau and DACO(local BBB) and those have help expedite some information about the problem all GC with auto leveling rear shocks.
They are not even allowing anyone with the problem to leave there vehicles in the service area if your have the problem and you have been already upgraded to the AD shock update by the TSB announced in April. They just wont take you car for a second update until the new update is out of back order.

Not the sound we all have at almost no speed over rough roads.

Re: Wk2 Rear Knocking Noise Aussie GC Laredo

(limited J.G.C 3L TD 2011 - self levelling shocks)

Hello, we have had another set of rear shockers installed, as a result of jeeps 2013 TSB directions (shocks changed to type C, I think). These shockers lasted about 500km until the chatter re-occurred, and it is now worse than ever. The dealer's line is that we are the only local clients that are complaining about this problem, but that jeep expects the chatter to occur in all of these JGC's in time. We are now wondering if we are exasperating the problem as we regularly tow a 2500kg caravan - but these vehicles are advertised as tow vehicles. We are over it, as we have now had this problem for 30,000 km. We contacted the shock absorber - after market suppliers, to be told that no one has after market shocks available for JGC, due to difficulty in integrating with the JGC computers. They recommend that we request jeep change our self levelling shocks to standard shocks, has anyone done this?

Re: Wk2 Rear Knocking Noise Aussie GC Laredo

Hi all,

I also have the same problem. My 2012 JGC Laredo has 22,000 KM and I first heard the noise about 500 KM ago, contacted my local dealer (Costa Rica) and they said the have had problems with the self levelling shocks and they would change them for regular ones under warranty. They did and the noise reappeared just after around 400 KM (weekend beach trip, travelled through dirt roads).

So... A few questions (bear with me)

Is the problem limited to SLS or does it apply to regular suspensions?
From the codes @Milous sent I see that SLS is actualy called SES, is this correct?

What are the downsides of SDA vs SLS (not considering towing)?

Shouldn't my jeep have come with SDM (Export suspension) being in CR? Is SDM a problem also?

Has anyone tried SDE?





I asked the dealer for the codes of the suspension I had previously and the one installed now, will send this when I get it.

------
Just to refresh the codes @Milous sent:

SDA - Normal Duty Suspension
SDE - Sport Suspension
SDM - Export Tuned Suspension
SER - Quadra-Lift Air Suspension
SES - Rear Load Level Suspension
SDX - High Performance Suspension (SRT only)

Thank you everyone this problem is very frustrating and I apreciate the group effort to solve it.

Hey guys, thanks for joining!

The problem with rattle was on standard shocks (3 TSBs out to fix it and looks like one of those was successful), SRT shocks (1 TSB out and a computer fix, which was apparently successful, too ) and the SLS (by the way SLS stands for Self Leveling Shocks, no a formal Jeep abbreviation).

First of all, the rattle can also occur when other suspension parts fail like worn bushings etc. as well as have other causes (somebody had loos tools in the spare tire compartment). Only proof that it is the shock is to replace I with a new one and see I the rattle is gone (not my preferred solution, however).

By the way there is no computer involved to these shocks, only to the SRT ones (for adjustments of the dampening) and the Airsprings. The SLS are a 'regular' shock which levels the car by the pumping effect during driving. Basically the shock pumps itself back up. No other power than loading the car is necessary. Lots of people get confused and mix them up with the Airsprings (they are adjustable using a compressor).

You can exchange SLS with regular shocks, just be careful to replace the springs as well. They SLS are taking some of the spring work, so the spring that comes with the SLS is a little weaker. As a result, your Jeep will sag if you don't change the spring.

Hope that helped

Re: Wk2 Rear Knocking Noise Aussie GC Laredo

Hi
I have just had our 4th set of shockers installed on my 2011 JGC diesel - that makes 5 sets of self levelling shockers, when counting the original set. The chatter started coming back after about 500k's. I thought the problem was towing related, so did not hang anything on the towbar for the 500k's, but the noise has reoccurred.- My dealer now won't discuss this issue further as they are taking the jeep official response that the rear shocker chatter is normal. Not many new comments on this thread, so are there any other threads covering this issue, or am I the only one still with problems?

Re: Wk2 Rear Knocking Noise Aussie GC Laredo

I had the SLS shocks replaced last summer on mine. It had been nice and quiet until now. What changed, you ask? I washed the jeep for the first time since I had the repair done.

Even though I drive it almost every day (during the winter), it's at pretty slow speeds and it stays remarkably clean. I drove to another town while the roads were slushy and it got dirty so I washed it.

If you want a quiet smooth rear suspension, just don't wash it.

I have self leveling shocks too and got the noise after a week of driving, the dealer changed the shocks already 3 times . The first 2 times it did not help at all, the third time the noise was gone but only for about a week. Soooo tired of this. Such a shame for jeep. It's a brand new car at the end and they charge money for this package.

Re: Wk2 Rear Knocking Noise Aussie GC Laredo

Hi guys, I just test drove a 2012 3lTD with 30,000 on clock and I could only just hear the shocker noise even though they still had the original self levelling shocks (not fitted with quadra lift) & had consistently been towing an 1800kilo van.

My shockers - now 1500km old - rattled 4 times as loud as their jeep did. Do you think that jeep has done a fix on this newer model & not told us? eg: stronger springs fitted - or a modified suspension?

Re: Wk2 Rear Knocking Noise Aussie GC Laredo

Has anyone had any success with after market rear shockers/air shockers? My understanding is that there are none available!
