I have a 92 integra with a front end vibration that I've been unable
It's most noticable above 40 mph and feels as if the front is out of
alignment or a tire is out of balance. At 65+, especially when the
road's wet, the front feels loose like it's floating or skipping
across the ground. I've done many of the typical things but to no
avail. Before I end up replacing everything I was hoping someone might
have an idea, the shop dosen't. I've done all the work but have never
worked with rack and pinion before, possible cause, I don't know..
Listing over the past 6 months
-alignment & balance 2x
-new rotors & brakes
-motor mounts all (one broke, trans mount good)
-new axles (one was bad replaced both)
-new lower ball joints
-new axle bearings
The bushings appear to be ok but I haven't looked at the rack & pinion
The vibration is a little more noticable under acceleration but is
still there during deceleration. It's most noticable if I'm running
say 65 and put a gradual load on the car. It has a wooble sound like
a tire out of round, out of balance, miss aligned. Someone mentioned
the camber and I know from one of the alignments that the passenger
side tilts in at the top. It has me baffold, I've worked on cars most
of my life and can typically solve a problem within the first (or
second) attempt. In some ways it feels like something in the
drivetrain (axles, bearings) and in other ways it feels like something
in the suspension (bushings, ball joints) it's got me?
Car is stock and I've tried a second set of wheels and tires with the
same results. Changed or checked most typical things associated with
a front end vibration.
One of the few things I haven't checked is the intermediate shaft and
bearing which may explain why it feels like drivetrain/suspension.
Hopefully I get a chance to take a look at it. I'll keep you posted.
Interesting. I never thought of that one.
That center bearing is under very little stress, but it's worth checking. I
should check mine for wear next time I pop the driveshaft out. I never
thought to inspect it when I had the shaft out last fall.
I have a similar thing that I've also been unable to solve, which is why
I ask. But mine is only on acceleration, it disappears completely on
decel. It's also much worse in cold weather than in warm.
The fronts should be straight up and down. If you've got positive
camber, you've got a bent part or worn bushings.
Check the tires themselves. Raise the front wheels off the ground (car
on stands). Start the engine and allow it to idle in 1st gear. If one
wheel won't spin on its own, give it a push with your hand to start it.
Now observe the tires from the front. Do they spin true? Do they hop up
and down, wobble side to side, or squirm both ways? If they do anything
but spin dead-true, there's a likely candidate for your problem.
Shut the engine off. Check the tire tread by gently running the flat of
your hand both ways over the tread. Dead smooth? Waves? Ripples?
Sawtooth pattern? Uneven wear left-to-right? What do you feel?
