    6MT Allroad shifting thud sound?

    Guest-only advertisement. Register or Log In now!
    Life happened and my project is now my daily. 2003 2.7T Allroad with a manual transmission and 166,000 miles. No service records on transmission or clutch. I think it is safe to assume the clutch has been addressed at this point, maybe not.

    When I engage or disengage the clutch on upshifts I hear and also feel a thud from the drivetrain. I dont feel it in my foot I feel it in my seat. Ive tried all different ways of transitioning throttle with clutch engagement and its almost always there. Downshifts to a stop are 99% thud free and I can rev match just fine. Downshifts for accelerating are 50/50 on the thud. My logical mind says It has 166,000 miles and the bushing and mounts are all tired and shot, shit is moving too much.

    Anyway, heater core was clogged really badly so I replaced it. I didnt realize it at the time, but I messed up the brake switch and had to get a new one. Is there potential I did the same with my clutch switch, it was removed also? It disengages cruise control just fine, but Ive found a couple posts about that switch causing issues on other members cars, hence my allusion the rev matching on downshifts and shift noise. Any guidance or experience is much appreciated.

    probably trans mounts and/or diff mount maybe even motor mounts or snub mount

    and if you ever find yourself on the central Oregon coast hit me up we can talk allroads! haha I'm the only euro/audi/allroad/anything besides lifted trucks and Honda guy out here.
    I also have access to a lift we can check all those mounts

    ^These. I used to get a thud and all my rear diff mounts were toast. Replaced with the Apikol set. Pricey but worth it, I think.

    The giubos on my driveshaft were also worn, contributing to some motion there.

    the giubos? is that a typo or something I'm not familiar with?

    The main culprit is rear differential mount IMHO, that one allows the rear differential to hit the metal brace and is right under the rear bench. Besides that, the tranny and engine mounts are probably also ready to be replaced but these usually don't make thud sounds when they go.

    Apikol absolutely not worth it , this is after 4 years or so:




    You want to buy OE bushing 4B3599381 (you can get it from fcp groton), fill it with polyurethane 3M window weld to add stiffness to rubber and press it into factory bracket. It will cost literally few bucks and will far outlast apikol with similar stiffness.

    Thanks for all the responses. You guys are rad! I was fearing something transmission related and getting nervous. Looks like Ive got more mounts to add to the ever growing list of parts and mods.

    A big skip, completely unnecessary. It will add a lot of noise and vibrations. Get a set of good transmission mounts first and if you think you still have movement then address engine mount and look at snub as well.

    I would recommend 034 street version because they're a solid chunk of galvanized rubber and their bushing is captured in the rubber as well, which is the main reason why OEM style mounts are superior to poly one if made with stiffer rubber that is. The weak point and reason why poly mounts are crap is because they are always made with free-floating bushing which with time destroys the poly from inside out due to inherent rubbing between housing-poly-bushing interface.

    More bad news to apikol crowd, these are my apikol transmission mounts after about tops 3 years. My apikols' poly got squished with time leaving a lot of slack in the mount which resulted in a lot of movement and jerking/thudding of the whole drivetrain. Basically the moral of my story is: don't buy anything made entirely of polyurethane (and yes, these are fully "compressed" and assembled mounts...):

    Sure you could, I don't see why not. I went back to stock bracket + new Lamfoeder bushing which I filled with poly to fill all the stock voids in the rubber. Once that settled, I pressed the bushing in which really compressed the poly inside so it is like a solid mount now but has the bushing captured in the rubber. If you look at my apikol mount that failed, it is clear that poly basically got smeared around by the combined weight of differential and heat generated by friction between sleeve and poly itself.

    Thank you sir. Appreciate the insight. Ive already got 034 engine mounts and transmission mounts in my wish list.

    Julex, do you think your setup from a power standpoint had anything to do with the wear on those mounts? Your turbos are pretty small...

    Rear differential maybe because there is a lot of twisting there when full torque hits but then the mount is marketed as racing mount so why would it fail in this way due to torque? .

    Tranny shouldn't. The tranny mounts are simply squished due to weight of transmission riding on them all the time. There is no weird wear on them like on the rear differential mount... just evident compression and deformation.

    Agree on diff mounts as likely cause. The parts car for my 6mt swap had urethane filled stock ones that I first had installed when swapping diffs. I was having some driveshaft alignment issues so I swapped my original mounts back in thinking maybe the filled ones were not lining up the diff right... Had a clunk ever since.

    Removing them did eliminate some road noise though it seemed and was hoping I could just keep it like this.. I already reluctantly have street density engine and trans mounts since this is my quiet car and the one we use for road trips. But I'll be getting new busings and filling them like julex mentioned. Just with something not as rock hard as the previous owner used.

    Finally got around to checking on mounts and FCP says that part number only fits 2001-2002 and I have a 2003. Anyone have advice on this? I know APB vs BEL makes a difference and Im a BEL.

    whole carrier with bushing 4B3 599 285 A

    front bushing 4B3 599 381

    All the same not sure why someone is saying 01-02 only.

    Mine were pristine at 15y mark. They see very little stress. It is the front one that gets all the action.

    People assume that stiffer performance mounts last longer which is incorrect. Urethane isn't as robust as rubber.

    I used Apikol rear bushings inserted into the front housing, they were perfect fit. Cost $60 for 2 sets, so even if they go bad after several years, I have a spare set. Then again, I doubt I will put more than 300hp out of my car, so they may hold. I also replaced the center support bearing/bushing at the same time as it was also bad.

    Is the driveshaft support bearing a total pain to replace? Ive been mulling that around as I wait for life to give me a much needed wrench break.

    I gave it a whirl and couldn't get it undone, but might've been approaching it now. I heard 034 did one a long ways back but had to build a custom jig to hold the damn thing in order to try. I am thinking of trying Colorado Driveshaft to see what they can do for me. Emailing them doesn't seem to work though.

    When I rebuilt mine I couldn't get the bolt off (it had some marks and looks like someone tried before) so I just ended up impact chiseling the head off, extracting what was left of the bolt and now it is a stud and nut.

    I've got a brand new allroad bearing if anyone needs one.

    6MT Allroad shifting thud sound?

    IMG_3628.jpg
    Diff mount is out and completely torn on the lower half. Ding ding ding. Now to install the new one. Shop press for this bad boy?

    I finally have my project back! My better half got her new car, finally. Used 2018 SE Alltrack 6MT with 2,200 miles for $23,000! I think we scored.

    Long story short, according to the machine shop thats the wrong part. 70/1000 too big and hes afraid to press it in and break the support bracket. Called up Matrix Integrated and they dont list a part# for a manual Allroad rear diff mount. Its grayed out and he cant see a part number. Hit up Audi Wilsonville and the parts manager says theres only one part# listed for that and I have it.
    I ended up ordering the entire support with the bushing in already, 1 of 3 in North America, and Im hoping this solves my problem. Damn! Wish me luck!

    The diff bodies are the same between manual and auto, so I can't see why the bushing would be different. I would've tried wire wheeling and sanding the inside of the mount bracket to get rid of corrosion and pressing in the new mount, that's usually all it takes.

    Part# 4B3-599-381 for the bushing itself and thats the only part number listed with Audi. I find it weird that Matrix couldnt tell me a part number because it was grayed out.

    Part# 4B3-599-125 for the whole shebang with the bushing installed.
