    do you know for sure a tire is not seperating and this is not the cause?

That could cause the vibration but I have also seen brand new tires out of the blue seperate or through wheel weights and cause dashes to vibrate so I would eliminate that completly from the equation.It wont cost you anything if where you had them installed does lifetime balanceing.

Vibration and banging noise in front end right in fornt of center console on the floor board I think its the u joints? But I have to get two guys to believe me on this. The banging noise is only when...


Sounds like U-joint. Also check front driveline shaft on 4x4, sympathetic motion can sometimes turn shaft when not in 4x4 mode.

With play in U-joint, joint slips to one side as Torque pushes against flange to turn driveshaft. Basically U-joint is cocked and shaft is not running true to center plane.

Also worth checking are front c-v joints if 4x4 vehicle. Pretty much the same problem can exist with these small joints as with the big joints on your driveshaft.

The last areas are the motor mounts and transmission mounts. These can cause the same problems you describe. And remember that sound transmits differently through metal.

Vibration rumbling coming from front end of a 1997 chevy blazer 4 wd


You still have hubs, and the front driveshaft. On some models the front driveshaft can be removed leaving the pinion forks/ ring in place. Some other Transfer cases may use an output shaft thats like the tailshaft on an automatic. This style could leave a gapping hole when you remove the front driveshaft.

Tires are a problem once a wear pattern is embedded in the tread. Sometimes a front to back rotation will reduce noise.

A caliper could be stuck skipping over a turning rotor.

I have a 2006 chev 2500 HD. The steering wheel and 4x4 shifter shake very bad at 50mph. It has had a new transfer case put in, driveshaft balanced and all four tires checked. The vibration goes away if you...


u need to check rear end with the drive shaft removed vibration goes away would lead me to believe you have bad bearings in the rear end more than likely the pinion bearing
pull cover off (while fluid draining check to see if there a lot of metal in oil )
if you do see metal in fluid or laying in rear end you need rear end rebuilt or replaced
i wouldn't recommend doing the rebuild your self because with out the special tools and knowleage u can make matters worse

While checking my transfer case seal, I noticed some play in the transfer case when I push up on the drive shaft. Should the transfer case be ridgid or is a little play up and down ok?


Hi, there is a small amount of up, and down play, as the driveshaft has to work back, and forth, on the splined slip joint in this particular area. There is a bushing in the rear of the transfer case as well. Between these two things, the play is normal. May seem a bit too much, but normal. Good luck...Coop

How do you get the front driveshaft out of 2001 chevy 4X4


Remove transfer case shield. Remove clamp on boot
where front drive shaft meets transfer case. use a flat
screwdriver to pry free end up and release clamp. (you need a special clamp tool to reinstall clamp )
Remove 4 bolts at differential end that hold U joint Retainers to yoke. Slide drive shaft to rear enough to clear yoke. then let drive shaft drop so it clears differential and slide forward until it come off transfer case shaft.

Wobbling/vibration coming from back, steering wheel doesn't shake. I feel it in the seat. Got new tires and I still feel it. Had drive shaft checked, and mechanic said it was ok. Axle seals were leaking,...


Did the mechanic remove the rear driveshaft to check for a binding U-joint or just check for loose u-joints without removing the shaft. You need to remove the shaft to do a good check of the joints

What do i need to do to convert my c-6 4x4 tranny into a 4x2 tranny


get a 4x2 tranny, and replace the 4x4 tranny and 4x4 transfer case with it, you will also need to remove your front drive shaft, that operates your front FWD, and replace the drive shaft for the rear axel.....

Find a good Salvage yard and see about trading parts to convert to 4x2
