whitesupratt Posted January 5, 2006 Share Posted January 5, 2006 A little while ago, i mentioned that my car was very unstable. driving funny with a 'wiggle'! And that the backend was very very and wrongly lively!!!! It also juddered from the rear when pulling away, like wheel spin but not! And the steering was off centre when driving straight! Anyway 3 weeks ago I got a full geometry check, it turned out that 1)my rear Passenger tracking was well out! 2)front a little bit 3) my wheels needed balancing as well! That seemed to cure! drove nice, steered straight! NOW! suddenly, all those symptoms are back!!! HOW can a car, just 'UN Track' itself???????!!!!!!! I would know if id hit any pot holes, or kurbs etc! Quote Link to comment Share on other sites More sharing options...
Homer Posted January 5, 2006 Share Posted January 5, 2006 This might be a silly question, but did you have the tracking alignment done before of after the accident? Quote Link to comment Share on other sites More sharing options...

Steve W Posted January 5, 2006 Share Posted January 5, 2006 That's what i said ! Mine's doing it AFTER Four Wheel Alignment !?! Maybe it's me 18's (they're much stiffer than the old 17's !) ? Maybe the 18's show-up bad shocks that were hidden by the 17's ?? Maybe the shocks are actually a bit on the stiff-side anyway ??? It just gives a funny 'unsure' feel, ya know ? Not dangerous, just unnervy. It's probably FINE, but . . . . . . . Quote Link to comment Share on other sites More sharing options...
Paul Whiffin Posted January 5, 2006 Share Posted January 5, 2006 It could be a number of things, dodgy shock absorber, brake seized on, something bent, tyres worn uneven, etc. etc. Better get in there and have a butchers me thinks. Quote Link to comment Share on other sites More sharing options...
whitesupratt Posted January 5, 2006 Author Share Posted January 5, 2006 Yeh but mines, not just unstable. The steerings off again! and when i pull away from stand still the rear shudders as if its loosing traction! Its just gone from fine to exactly how it was before! over night! This is all after the crash! i got it sorted after the crash, not its buggered again! all by itself Quote Link to comment Share on other sites More sharing options...
JohnA Posted January 5, 2006 Share Posted January 5, 2006 It could be one of several things. When I got mine it was pulling to the left, a lot! I expected it to be a dragging caliper or an alignment issue. Proves out that it was a couple of missing bolts from the undertray. YES, the air was moving assymetrically under the plastic undertray (which looks flimsy when taken out) and that was enough to make the car pull at speed. 20psi tyre pressure difference wouldn't make it pull as bad as it did. Lesson: the supra is very sensitive to parameters that do feckall in other cars Quote Link to comment Share on other sites More sharing options...

A lot of the alignment centres around do not tighten them up enough, you drive off down the road and soon enough its all out again and your car is feeling strange again, trust me on this one, it happens all the time.

whitesupratt Posted January 5, 2006 Author Share Posted January 5, 2006 oh, could be that! the strangest thing to me about it all is that, it got sorted when i had the geometry all done, that was after the crash, and it was spot on. and now all by itself if up the spout! the wierd thing it must be the passenger rear again, that really shuddered when i pull off! your get the bang bang bang as if your trying to wheels spin but getting too much grip!

toyotasuprauk Posted January 5, 2006 Share Posted January 5, 2006 The chassis bolts could also be lose, thats certainly worth a try. Quote Link to comment Share on other sites More sharing options...

Is it wheel hop? If so it could be a worn damper, top mount or suspension bush. Quote Link to comment Share on other sites More sharing options...
Pete Posted January 5, 2006 Share Posted January 5, 2006 Proves out that it was a couple of missing bolts from the undertray. Really!? That's amazing! I'm off to check for missing bolts Quote Link to comment Share on other sites More sharing options...
whitesupratt Posted January 5, 2006 Author Share Posted January 5, 2006 Is there anyone of you supra 'experts' on here that are reasonably near me that would be able to have a look on saturday at anytime at all? even if its to take mine out for a spin. iv never driven another one so do know how mine compares to others. I know my steering wheel shouldnt just over night be on the wonk! Some that knows supes, and that i know isnt going to abuse my motor? I only have sats/suns off! I cant afford much money, so dont really want someone who is going to look further and further and then take more apart and more apart then give me a big bill at the end, jut want an experts opinion! co if it is tracking again ill take it back to who did it!

Homer Posted January 5, 2006 Share Posted January 5, 2006 Why don't you just take the car to Phoenix in Watford for an afternoon's testing? Quote Link to comment Share on other sites More sharing options...
Guest cuemaster Posted January 5, 2006 Share Posted January 5, 2006 hi from the usa, i replaced my bushings with urathane, new shocks, springs, rotors and rubber,feels like new now. id look at your bushings and tires, ive had two mkivs over the last 10 years and both those things have caused those types of vague handeling problems for me.

JohnK Posted January 6, 2006 Share Posted January 6, 2006 Make sure your subframe bolts are not loose Quote Link to comment Share on other sites More sharing options...
Ian C Posted January 6, 2006 Share Posted January 6, 2006 excellent, ill get them checked!...Homer, arnt phoenix going to charge bucks tho. like...per hour! Yeah, but ) not too many bucks, b) they will take car eof your car, and c) they will probably find what's wrong with it. -Ian Quote Link to comment Share on other sites More sharing options...
whitesupratt Posted January 7, 2006 Author Share Posted January 7, 2006 well...took the car to where i got the geometry done, they checked it all over with me there. its not the geometry, and nothing seemed bent or loose!!! but the knocking from rear is getting worse when i pull away! i think its job for phoenix Quote Link to comment Share on other sites More sharing options...
whitesupratt Posted January 7, 2006 Author Share Posted January 7, 2006 Me and a mate have narrowed down the symtoms! It knockes and shudders from the rear when pulling away and turning and the same time!, if i pull away in a straight line its not too bad! And when hitting a bump the rear jump around violently! so.. could it be a)diff? b) the common problem of loose subframe? Quote Link to comment Share on other sites More sharing options...
dangerous brain Posted January 8, 2006 Share Posted January 8, 2006 Diff is a good place to look but how would you test that??? Experts??? Quote Link to comment Share on other sites More sharing options...
whitesupratt Posted January 8, 2006 Author Share Posted January 8, 2006 Right... i took the supra to my local VW workshop (my mate works there, let me use the ramp)! It was a ramp that lift the car from the sills, therefore the wheels were hanging free! This is what we found: Everything that uses a nut or bolt is F**king tight! Nothing seems bent I drove the car through the gears, with the wheels free spinning, and everytime i hit the throttle, or changed gear the diff moved a lot! (but remember, was just hangin, with no weight of car on it! Its deffinatly coming from the passenger rear! Top mount is tight! Its getting worse and worse, the car wonders all over the road violently! Everything i pull away, fromt the outside of the car, the rear pass wheels, shudders violently, and it pull the top of wheels into the arch! And theres a loud knocking with it!

Jspec Germany Posted July 10, 2006 Share Posted July 10, 2006 Did you ever get this fixed? Mine "wiggles/shimmies" a little from side to side while driving normally, like the wind is blowing the rear end around back and forth. I torqued the subframe bolts to spec, but still does it.

I torqued the subframe bolts to spec, but still does it. sounds very similar to mine mate, but it's intermittent. as you say it feels like it's being blown from side to side and the subframe bolts being tightened did nothing (nor did a full geo setup). any of you guys still having this problem? what have you tried? what sorted it if it has been?

Paul Whiffin Posted October 6, 2006 Share Posted October 6, 2006 Sounds like wheel alignment or tyre pressures to me. Have these checked ASAP. Quote Link to comment Share on other sites More sharing options...
