Default HELP Uncontrolled chassis movement


see video for problem

no suspension play

new shocks in rear

*** meter tells me the problem is with the right side of the car but that's not always correct

only happens above 65 when turning left HARD

sometimes notice handling imperfections at lower speeds again turning left only

looks like possibly the toe is not aligned right in the rear. My 96 accord did this in the winter. have you had an alignment?

Man that is severe. I would give all the running gear a thorough check
over. Something is badly out of whack. Check your wheel alignment is ok,
check your tyres (sometimes a bulge in the surface can be a big problem)
+ balance of wheels. Check all your suspension system, shocks, springs,
bushes. Look for any damage to control arms etc. Check rims for any
damage distortion. It would help if you can also advise what springs
shocks you are running and if they are adjustable what settings you are
running. In the meantime i would be fn extremely careful driving your lude
until you diagnose the problem. Also has the lude been in a serious
smash at some time, maybe the chassis is out of alignment. GL with it.

No and your not the first to recommend. I'm really stubborn and feel this isn't the problem but I'm starting to think it just might be

Damn yeah, get a good frame and body shop to check your alignment and frame out for sure, that is sketchy at best! I find old school frame guys with a really good machine might be best for this one!

The alignment shop I use found a ball joint going bad on my WRX, couldn't even tell driving it, but they wouldn't even align it, as they were afraid it could skew the measurements if it moved. New ball joint a week later and all was good.

More info would help. What suspension are you running and what settings? Also
have you got the lude on a hoist and done a real good inspection of everything?
Checked the alignments and the chassis?. If your stumped you really need to get
a good mechanic to look at it. Can't really diagnose the problem from a video man.

That looks like something going on with the radius rod. I've had two radius rods snap and the piece just sits in there it doesn't even fall out. Grab the radius rod in the front and see if it's loose. Just a thought.

Have you had an alignment done as everyone is recommending ? They can and SHOULD adjust the caster as well. A lot of shops think you can't adjust it but it's completely adjustable by adding 1/8 degree shims in between the radius rod and the subframe in the front.

No play in my radius rods. And the method your talking about for adjusting caster is for the base model preludes. To adjust caster on the sh models you have to swap radius rods..... Thanks for your help though

So the front tie rods (inner and outer) barely had any play but the boots were bad so I replaced them. At the same time I got new rear tires and an alignment. After that the problem has disappeared.
