Front End Shake~

[Powerzen2002]

oK, my car/car wheel wont stop shaking! I DONT KNOW what to do! I tried putting 4 brand new ... balanced tires,very very little change if not none. I do need an alignment, however i doubt that has anything to do with. The car has never been in an accident, only has 71K miles on it.

Could it be a wheel bearing? I dont really hear it roar'in, but
maybe? Any ideas?

I also dont see a leak near the rack and pin ... so i assume that is
good, plus i replaced the two lower tension bars.

Oh its a 90 240sx .. and shakes at 60 MPH - 85 MPH ...

PLEASE before I go INSANE with the shakes.

Thanks~!!

P.S. What about a steering stabalizer or something? I need
to do something fast! Thanks!

Bent wheel, warped rotor, flat spot on a tire, poor balancing job.

The first thing you can do yourself is jack up each of the front wheels and try to feel if there is any play in the ball joints, hub or tie rods. Also, check the boots on the ball joints to see if they are ripped, usually when they are ripped they go bad real fast. If you can't find anything, then you'll have to bring it to an alignment place and ask them to find something. They will and they'll want to charge a lot for it. They will usually tell you what is the problem, then you can just do it yourself and bring it back for the alignment when you have replaced the part that is worn out.

Not a bad on idea on gettin the estimate then doing it myself...

BUT ... i am thinkin warped rotor also! Because, when I goto
stop ... pressing on the brakes at high way speeds the car
and wheel shackes VIOLENTLY. ... .... i am going to assume
rotor also. But is it possible for a semi-warped rotor to make a
wheel shake when just driving, not breakking?

Thanks.

Nope, My car does the exact same thing. New rotors. My problem is due to bad TC rods and one bent wheel. Plus some of my rubber boots on various LCA's are leaking goo. But I don't think that contributes to much to the problem.

Check/replace TC rods first as they are the cheapest.

Dunno if u checked your TC rods but this is a common problem at exactly that speed w/ a worn out TC rod bushing...
get a pair of whiteline bushings, solved same problem for me overnight, tightened up steering significantly and didn't cost very much.

A good idea whether this is the problem or not.

The TC Rod's look like this :

0====0 ???

Like, they are connected down by the lower control arms??
If that is what your tlakin bout, I replaced both .. (driver
and passenger side.) No difference at all since the replace-
ment.

Nope they look like: 0------0-0sa98f....hold on.....

0----'-' um......there!

Big rubber bushing, 11mm bolts.

I dunno, i looked in my chiltons and all I see are:

Tie Rods, Lower tension control arms (which I already
replaced with OEM's from Nissan), struts, wheel bearings,
roders and brake assembly's, nothing else....

Im gonna check my tie rod bushings today also ...

Dunno ... if someone could tell me what the TC rods are
connected I will check it out.

THanks.

I'll give ya one guess what "T" and "C" stand for in "TC".
