oscillo hero

i have tracked down the cause of the problem. the fluid in the transfer case was badly burnt and past its prime. the fluid in the rear near the hatch only activates the awd and it was fine. the oil i changed was in the centre diff off the side of the transmission. i used castrol transmax z and the shudder is all but gone. reading the manual a little bit of a braking effect is normal but the amount i had was pretty severe. thanks for your help guys

i did the safety check and was told that the cvs were fine and so was the tie rods. he seems to think the rear difff locks and causes the clunk. as burkey said his used to do it so is this a standard thing or are we just special. i might change the attessa fluid to as most of the mechanics would probably miss it. i asked one and he couldnt tell me what the oil was for.

sorry i havnt been able to reply in a while cos i was outta town. i might put it in for a safety check ike yous suggested. the tie rods/ends should be fine as i replaced them about six months ago. the problem was still there before and after. i also had the cvs cleaned up about the same time, apparently the boots were split but the cvs were fine so he cleaned them out and put some new boots on them. ive also checked tyre pressure and its fine. i also recently replaced the front stabilzer bar linkages which were worn. as for the 4wd use i rarely use it. maybe for 5 min or so every 2 months just so it gets some use. ill book it in for a safety check and let you guys know. thanks

hi im new the site so please bare with me as i cant find any info on the topic yet. i got a 97 rs4 stagea and when i do a slow u turn the front of the car clunks and shudders in sync with one rotation of the tyre. im new to mechanics and dont know where to start. the clunk is worse in 4wd or when reversing. it shakes the whole car a bit and can be felt through the steering wheel. while driving straight or doing a standard corner its fine and is quiet as a mouse.
