steering rack, vibrations on highway

[Losiracer2]

I was just wondering, if both of my boots are kinda torn and the rack is leaking PS fluid, would that cause a vibration on the highway at 60-70? The PS still works, its just it leaks fluid too, the reservoir would go from the upper to lower line in about 1.5-2 months time so it constantly drips whenever the car is parked. And no its NOT my:

-axles (new 5K ago, both)
-tires being out of balance (only have 1K miles on them w/ new wheels)
-alignment (got done about a month ago)
-warped rotors (20K miles on Powerslots w/ Hawk HPS pads)

or anything like that causing the vibrations, its just when i'm on the freeway...sometimes its shaky at 60-70 and other times its perfectly fine. i really dont understand how its happening either. its kinda frustrating

loose suspension components.

Check your bearings.
Check balljoints.
Maybe steering rack is screwed but I doubt it.

don't bearings only go bad if you hear a humming noise? hmm, what about tierods? do those come loose or go bad over time?

yeah you're right about the bearings. tie rods comes loose too. I think all suspension componets goes bad. Especially the bushings. Right now I replaces my UCA and to find out I have a leaking axel. AYE CARAMBA!

Tie Rods dont come loose. The bushing wear out.

I seriously need to take a rest.

yeah i just dont get it though, it doesn't squeak, i just jacked up my car and the balljoints in front are fine, moved the wheel L-R and top to bottom on each side and no play. I even jumped up and down on the front end to listen for any squeaking, and nothing.

Its like the wheel shakes, not a vibing kinda shake, but the wheel actually moves L-R when i'm at that speed. but it doesn't feel like there's any real play.

[Losiracer2]

do the hydrolic arms in the steering rack over time lose pressure? so that's why the wheel doesn't feel rock solid at that speed?

[deevergote]

I wouldn't count out wheel balance or alignment. Just because it was done recently doesn't mean it was done right... or that something hasn't been done to change it.


Check all your bushings and ball joints. If they're good, that rules that out.
Failing power steering wouldn't do anything. I have NO power steering, and all shakes and vibrations are explained.
A failing rack would make turning difficult, but I don't believe it would cause vibrations.


Don't rule out the most obvious causes because you're "sure" they're not the case... Shaking at higher speeds is usually wheel balance.

control arm maybe... mine is about time for a new one.. it shakes a lil around there.

[Losiracer2]

hmmm, i guess i can have them rebalanced, but i literally bought the tires and wheels a month ago. I used to work for discount tire, so i had them "bullseye" balance the wheels to get them to zero out perfectly as opposed to being .25 off how it usually is when the machine rounds off. I even had them 180 the tire so it would require as low amount as weight as possible. All 4 required less than 1 ounce of weight for the entire wheel + tire to be balanced.

What bushing's usually fail so i can check those ones out first? Since there's tons of bushings on my car, I'd want to inspect the ones that most people have to fix alot.

the shock mount bushing gets tore up, also the radius rod bushings are beat if alot of burnouts/jerky driving has been seen.

it seems more and more accords with the same damn problems... you could have been describing my car except everything is new and proper working condition, but there is a shaking vibration ~60-70 that feels like the car is "wiggling" on its body

*note to deev.... ive been waiting at least 4 years for catch 22 to appear in a sig

I have the same problem

Does your steering whell shake because of this?

Does the shaking get faster as your speed goes up?

I can actually notice the wheel going back and forth while turning a left turn like it is something wrong with the right side of the car.

I need to fix this problem as well as others that my car has.

My VSS is out right now so that is getting done first.

where are the radius rod bushings exactly? does anyone have a picture of what they look like?
