Low speed Vibrations

Low speed Vibrations
Been getting a pretty significant vibration from about 20mph-5mph in my XJ. Vibration is just when slowing down. Thought the rotors may have been warped, replaced those since they needed it anyways but that didn't solve it. Cleaned the rear drum parts and readjusted them, but no changes. Rotated the tires since the front appeared to be cupped a bit but still getting the vibes. Checked the U-joints on the driveshafts and ball joints but don't see any issues with those. Any other ideas?

RE: Low speed Vibrations
Check the steering and suspension too. A loose tie rod, ball joint, wheel bearing etc. . . may cause a vibration while braking. At speed the tires have enough inertia to dampen side to side movement.

If nothing is obvious stop by sometime and we can pinpoint where it is coming from.

RE: Low speed Vibrations
I can only get a year or maybe 5-7K miles out of wheel bearings. Doesn't matter if I properly torque them (which I do) or buy timkens/cheapies. They just don't hold up to lower backspace and bigger tires.

Can't really tell without looking but that's been my experience.

RE: Low speed Vibrations
I always have issues with balanced tires, I'll get driveline shakes at specific speeds that make me think it's something else, then I'll get the tires balanced and it will be fine. If I put enough miles on the tires or run an incorrect pressure or get a new set the problem reappears, at different speeds.

RE: Low speed Vibrations
hmm. Reminds me that I need to balance my tires.

Took the BBs out well over a year ago

RE: Low speed Vibrations
Why did you remove the BBs? And did you use actual BBs, or airsoft BBs?

RE: Low speed Vibrations
I used regular BBs. It was fine at speed 45+. I could run 85 and it was smooth. But undriveable between 35 and 45

RE: Low speed Vibrations
since i deal with my commercial accounts and shops everyday, i make a lot of friends and am able to get my tires professionally mounted and aligned and balanced for free.
still, it seems like im getting tire work done all the time

RE: Low speed Vibrations
Had a chance to check some things out again the other day. Doesn't appear to be the ball joints, no top to bottom movement in the wheel. The tie rod ends have seen better days, but not any noticeable side to side movement in the wheel either. I noticed it has a wobbling feel to it when going about 15 mph, and the vibrations are now pretty constant at any speed, but much more noticeable when braking at low speeds.
