Re: Quadra Trac 2 Clunking Sound

re rear clunk on take off .
My 2011 wk2 Diesel with quadra trac 2 now has 45000 ks and this bump or clunk has developed over the last two services it was reported at the 30k and again at the 40 the service techs told me their info was that the bump was comimg from the transfer case and it had something to do with the 4wd system in their terms binding up and then being released hapening more often on slippery surfaces and then driving onto a firmer surface or when cornering or when the tyres have uneven wear or pressures . My issue is when slowing down for traffic lights or other intersections and either coming to a stop or slowed to less than 5 k's and then accelerating away and it doesnt have to be harsh travel a few metres and then clunk . I have been told chrysler are aware of the problem and are working on a solution . Would appreciate feedback from anyone who has reported to their dealership and what response they have been given.
Thanks for your time,
Sparky60

Re: Quadra Trac 2 Clunking Sound

Hi sparky60

My 2011 3.6 had the clunk from new and it hasn't really changed. I have complained about it at every service but the dealer doesn't have any solution. I also had the steering wheel clunk (TSB 19-004-11), which is now returning after it was successfully fixed with a new steering column shaft, plus other sounds and rattles which hasn't been fixed. I don't have the self leveling shocks which apparently also rattles a lot.

Your description of the clunk is good and I think the transfer case is the most likely cause. I believe we both have the MP3023 transfer case. Since you didn't have the clunk from new it does seem to be different from vehicle to vehicle though.

There is a STAR case S1121000013 about the 4wd system binding if there is a difference in rolling radius. My dealer referred to it and I have a paper copy. It is however not the cause of this bump/clunk which happens going straight out with no difference in rolling radius.
