Disco-Ron Posted December 1, 2008 Share Posted December 1, 2008 Be worth checking radius arm bushes, both ends, Panhard rod bushes....steering damper...... and even the front hockey stick bushes..... and lastly... tyre pressures!! Quote Link to comment Share on other sites More sharing options...

Orgasmic Farmer Posted December 1, 2008 Share Posted December 1, 2008 Definitely worth checking the trailing arm bushes, front ones would be my first suspects. Had a similar thing with mine which was most manifest downhill on motorways.. a bit scary. And check the preload too! Quote Link to comment Share on other sites More sharing options...

Guest weeble Posted December 2, 2008 Share Posted December 2, 2008 I presume youve had the wheels ballanced?. Could just have lost a weight!! Quote Link to comment Share on other sites More sharing options...
Rolly Posted December 2, 2008 Share Posted December 2, 2008 You didn't say if you had just come off a muddy track, any small clump of mud, fist size or less clinging to the inside or outside of the rim will play hell with the balance and result in a god-awfull shimmy in the steering or overall feeling in the car.

lrfarmer Posted December 2, 2008 Author Share Posted December 2, 2008 was a wobble that felt like the back end hadn't been off road, was on the way home after coming back from painton been driving fine was at the bottom of the hill and the car started to wobble Quote Link to comment Share on other sites More sharing options...
Guest weeble Posted December 2, 2008 Share Posted December 2, 2008 Jack up the rear wheels and check the tyres. Rotate them and watch them carefully. Look to see if the sidewall seems out of shape or the tread is uneaven. Sounds to me like a tyre may be about to fail due to broken casing structure. If this is the case you may have a bald spot on the tread. If they seem OK get them ballanced before looking too far anywhere else. Hope this helps!!!

PaulN Posted December 2, 2008 Share Posted December 2, 2008 any ideas. Yes even the onces i may have checked(or forgotten too) Sorry in advance about suggesting this but have you had the wheels off recently? The wheel nuts may have come loose! I'm usually very careful about the process of hand tightening, dropping the truck down and then tourque tightening properly when refiting wheels only a couple of weeks ago working late I forgot the second tightening on one wheel! Took 15 miles but loosen they did on that wheel and it sounded a bit like wheel bearings going, then wheel wobble and then whole vehicle shakes. Jacked up on road side and they were barely half a turn undone but what an effect. As I said - sorry for mentioning it as it's a bit basic but worth a looksee?

Orange Posted December 2, 2008 Share Posted December 2, 2008 Trailing arm to chassis bushes is my bet. Had it on a Range Rover - anything over 50 and it felt like the back end was trying to steer. Even worse on heavily rutted roads. Bushes didn't look worn at all, but with the new ones on, it was like driving a different vehicle... Bit of a pig to do, but made easier with a second pair of hands to get everything lined back up for reassembly. Quote Link to comment Share on other sites More sharing options...

Orange Posted December 3, 2008 Share Posted December 3, 2008 I can't promise that this will solve the problem completely - bear in mind that if those bushes are like that, it may be worth checking the others that other people have mentioned. You should notice a very big difference, though. Glad it helped... Quote Link to comment Share on other sites More sharing options...
Orgasmic Farmer Posted December 3, 2008 Share Posted December 3, 2008 Yep, you will be amazed. My disco used to self steer from the rear end when you backed off the throttle, especially downhill on motorways. Shot bush on the NS trailing arm to chassis..... I polybushed her after that. Was OK but massive increase in transmitted road noise. Quote Link to comment Share on other sites More sharing options...
lrfarmer Posted December 20, 2008 Author Share Posted December 20, 2008 the drive down was fine on the way back i loaded the 90 a bit too far forwood but wasn't too bad till i got to the same bit of road that it wobbled on last time. think i need to do the A frame ball as well as there seem to be a small bit of play.

A Frame Ball - that will be fun. I tried to change mine the other day, couldn't even loosen the two big bolts, let alon take it off. I understand that removing the ball joint from the housing is a real bugger also - Any one got suggestions or experience of this ? Filthy.

Filthy. gas axe and a very big hammer. or a big hydrolic press did the one on my 90 took the A frame off heated it up and hammered hell out of the old one but i did have a job getting the new one back in( could have done with a press) Quote Link to comment Share on other sites More sharing options...
