rednfast Posted September 3, 2014 Share Posted September 3, 2014 So I have replaced all the front bushes with Superpro (Control arm, Swaybar, Swaybar/Control arm mounts, and Steering rack), put in new Shocks since the old ones were completely busted. Put in a recond steering rack, got wheel alignment/balancing. Still at about 70-80km/h I get a steering wobble, and also when braking. Its way better than before I did all this but I am really unsure as to what it might be now? Only I ideas I have is the front tyres are a bit old (8 Years or so, and it sat for 4 of them), Ive heard they can get out of shape? Also could wheel bearings cause this? I am guessing the wobble on braking might be the front discs being warped? I recond the whole brake system not long ago apart from the discs. As for the gearbox... When I start the car from cold there is this intermittant scraping kinda noise which goes away after the car has been running for a few k's (engine temp does not seem to affect it). However once I have done 10k's or so, and I shift into 3rd or 4th at about 3k rpm it will make a rattle/scraping noise even on light throttle (definately not pinging, at ~2k rpm foot to the floor it will not make the noise till it gets to 3k). The sound then goes away after about 3.5k rpm. Could it be a stuffed thrust bearing? Or maybe the clutch itself? Any help apprectiated.

Ranter Posted September 3, 2014 Share Posted September 3, 2014 It is likely to be the tyres but the recent balancing seems to suggest not. I had a Mk 1 with a violent steering wobble once, so violent you could not hold onto the wheel, that was the bottom ball joints. Also had a brake wobble in an old Mk2 the was loose wheel bearings but you having done all that stuff already I'm sure you would have noticed excess play in them so discs is next best bet.

yetchh Posted September 3, 2014 Share Posted September 3, 2014 I'd say discs/bearings Quote Link to comment Share on other sites More sharing options...
Flash Posted September 3, 2014 Share Posted September 3, 2014 Are you running steel rims or mags ? I have experienced similar wheel vibrations with mag rims if they don't have a spigot locating ring. They run fine on a balancing machine as the machine uses the centre hole to spin the rims up. Quote Link to comment Share on other sites More sharing options...
ajg193 Posted September 3, 2014 Share Posted September 3, 2014 It is probably bad tyres causing the wobble. Getting them balanced will not fix the issue, it will likely make it worse. My old front tyre on my car got to a point where it was becoming elliptical, I did not know this is what was causing it to shake so I got the wheels balanced and swapped L<->R. This made the car drive horribly, it pulled to the side and shook like hell. A new (second hand) tyre fixed that and it has been perfect since. Once my front tyres run low on tread I will go and get some brand new ones. 1 Quote Link to comment Share on other sites More sharing options...
rednfast Posted September 3, 2014 Author Share Posted September 3, 2014 Are you running steel rims or mags ? I have experienced similar wheel vibrations with mag rims if they don't have a spigot locating ring. I am running on the orig steel rims. This explains a problem I had with an older car though It is probably bad tyres causing the wobble. Getting them balanced will not fix the issue, it will likely make it worse. I will try putting some new tyres on the front, hopefully that will fix atleast the wobble while driving. Then I guess Ill have to shell out for some new discs/bearings. I had a Mk 1 with a violent steering wobble once, so violent you could not hold onto the wheel, that was the bottom ball joints. I'd checked all the ball joints when I had it apart they were all good n tight. Thanks for the replies all, helped confirm my suspicions Quote Link to comment Share on other sites More sharing options...
QCADTA Posted September 4, 2014 Share Posted September 4, 2014 is the wobble more on the left front than right? Quote Link to comment Share on other sites More sharing options...
Brock-Lee Posted September 4, 2014 Share Posted September 4, 2014 How did you check the ball joints. Unless you got a pry bar and really tried to move them around you havent checked them properly. I argued with a WOF guy one time that mine were fine and I got shut down pretty swiftly hahaha Quote Link to comment Share on other sites More sharing options...
rednfast Posted September 5, 2014 Author Share Posted September 5, 2014 Replaced both front tyres and the 70-80km wobble is gone. The brake wobble is still there but I swear it does not feel as bad as before. I haven't taken it for a long drive yet so cant be sure. is the wobble more on the left front than right? I am not sure how I would tell that, the steering just wobbled side to side at 70-80kms or so. The steering pulls to the left even after wheel alignment so its hard to tell with the brakes without crashing as it pulls hard left when braking hard. How did you check the ball joints. Unless you got a pry bar and really tried to move them around you havent checked them properly. I argued with a WOF guy one time that mine were fine and I got shut down pretty swiftly hahaha I pulled them out of the car and had a look. Got the mechanic fitting the one piece bushes for the control arms to have a look. They were both nice and stiff with no breakage in the rubbers. The steering ones are brand new so I am guessing they're ok? Quote Link to comment Share on other sites More sharing options...
