Grip

Posted: Tue Jul 20, 2010 5:43 pm

something is up with my steering, It feels loose. When I turn a sharp corner i can feel it juddering even at 20mph doesnt feel like its gripping

Ive checked all bushes and there is no play and the trackrod end + ball joint is ok.

I have 195/50/15 tyres on and thinking these are too thin aswell as thoughts on tracking may be out, will be going for a 4 wheel allingment sometime next month

Any other thoughts to what this could, I am wanting to go to a track day soon but dont wanna go straight threw a corner with over steer

Hmm, interesting. I've never put anything but 195's on 15's.

When I get my new springs and negative camber I think I might be going for the tightest fit I can find to give some streeeetch Laughing

Well, since we've eliminated your tyre size as a problem and you don't think there's any play in vital suspension components...

Check your caster adjusters (the lip on the topmount - stock has them both pointing inwards). A 4-wheel alignment check is a good, free peace-of-mind check (though they're free to check, if they need adjusting they won't be). If you have worn (or cheap) tyres (or Pirelli P6000s) you might experience the same symptoms.

Mechanically you might have shagged ARBs, a shot CV joint (particularly if it happens more noticeably in one direction - check the outside one) or a knacked wheel-bearing (though you'd spot that in normal driving, unless you think blending spanners is a good noise for a car).

Incidentally, if you plough straight through a turn, it's understeer.

I'd also note that the 205 section tyres used as stock on the V6 are really pushing the edges of what you should try and put on a 6" rim - they're an 8" tyre!

I have been hearing a squek from the front may well be the bearing Wink

Will try find a free allingment garage to see if it needs dont

pretty sure the CV's are fine though will double check that
