wondering vehicle

audi a4 1.9 tdi 1999 155,000 mls,owned 8 years,mechanic for 20+ years,gets new front arms when required (its quite often on these isnt it) had new rear arm bushes,and a rack, and track rod ends,and all arms recently,BUT STILL WHEN THE WIND BLOWS, IT WONDERS OVER THE ROAD, on uneven surfaces (any uk motorway then) its 2 hands on the wheel ready to correct it when over 60 mph, over 90 mph is a full time job, i bet others on the road think im drunk. so anyway sort off at a loss now as to what the hell it can be,as my mind is working overtime on this problem, i thought today might as well do the front subframe bushes, just in case of poss self steer, then i will be at a total loss as to what it can be, DO ALL A4'S WONDER ALL OVER THE PLACE ?? if so im chassing a manifactures fault, then ill give up and get a bmw. any help greatley recieved,PLEASE GOD SOMEONE HELP ME!!!

Replace top suspension strut mounts...also top front suspension arms might be shot and track rod ends as well. Also, given the milleage and age of the car, the shocks might not be up to scratch as well !

cheers for the input, but has had EVERY arm and rear axle bushes aswell,and new rack and track rod ends in the last year and under 15k ago,and shocks done 2 years ago with new springs less than 30k ago, new avon zz3 tyers also, sort of gone to town with it, and at a loss as where to go now.

Do you get a rattling noise as you go over bumps ? maybe the top suspension mounts are shot or the subframe bushes are not tight anymore... If rear beam bushes have been replaced and all the suspension arms bushes are in good shape, then its only the top susp. mounts that might be faulty ! Also i suggest you take your a4 to a 4 wheel alignment centre, just to make shure everything is within spec.

yeh i was thinking subframe bushes, as strut tops dont actualy affect steering as there indirect onto bottom arm,was also thinking sod it and polly bushing all round for that tight yet rumbling feel poly bushes give you,but they stress arms to much and didnt want one snapping, oh, not knocking over speed bumps at all, quite smooth realy.thanks for input, hoping someone out there has had and cured same problem, cos the way im going the running gear will be all new soon.

i have the same problem and i wonder if you cured and how did you do it.
thanks

I have this problem too....starts at exactly the same speeds. I`m currently replacing many suspension components, which I know for sure need doing.

HOWEVER, a fellow A4 driver has had the same problem, and eventually, after replacing many parts without curing it, bought some new harder springs for the front shocks off Ebay for 80 quid the pair, fitted them himself, and now tells me his car handles fantastically, and grips better than he ever imagined an A4 would.

hi mate as the car been lowered if not why not invest in a lowering kit stiffer springs and shocks you can buy a koni STR kit from awesome gti for £265.00 all in. many moons ago i had this problem with an r reg a4 saloon so i fitted koni shocks and eibach springs it totaly transformed the car and made it a joy to drive
