Bump

 

How do you tires look??
Could be you need an alignment or when was the last time you balanced the wheels?

 

your tires still round? balanced? Hit anything recently to mess up ur alignment? stock or lifted? is it death wobble or just vibration? check ALL ur suspension bolts and bushings. I had death wobble on my 98 after putting on a 4.5" lift. Turns out my uca's were to short which screwed my caster/pinion angle up. Check the frame end of the lca's and see if they have the same amount of shims on both lca's.Thats how you adjust caster without adjustable lca's. Good luck!

 

Tires check out fine Got an alignment about three weeks ago along with a tire balancing about two weeks ago. Thanks

 

Stock height i believe tires are still round will check. Thanks

 

Don't go over 65 mph. That should stop the vibration.

 

Lol i wish my foot would allow that. Would a bad rear axle bearing cause a vibration?

 

Mine does the same, not a lot of vibration but you can feel it. Although it could just be the roads because PenDot sucks and can't fix any of PA's roads the right way.

 

Lol Well im sure its not the roads for me although i live in ky the vibration shoes its A$$ everywhere. I just noticed yesterday that it stops for a sec when i hit a bump like an over pass or something then it keeps on vibrating. Thanks for the input

 

if it feels like its coming from the front pull the front driveshaft and see if it goes away. They can be slightly bent or out of balance and cause a vibration. While its out jack the front up and ck for play in pinion and carrier bearings.

 

My 98 vibrates like crazy. I thought it was my transmission going out then thought it was my drive train but turns out my muffler is shot. Now it constantly rattles and makes a deep growling sound like a V8 when im driving and it sounds good.

 

Man, How come so many people on here have this issue, but noone knows how to fix it? I feel for you. I have the same problem. If I pull the ft driveshaft, it goes away, but a new one didn't help anything.....

 

Already did this man thanks For the input though

 

Well mine seems to be a drivetrain vibe no muffler could vibrate like this. Thanks man
