Transfer Case Vibration

You checked the oil in what?

When was the last time you CHANGED the oil in everything? Front & rear diffs, transfer case & transmission?

Did you check the u-joints for wear?

Did you check the carrier bearing?

Also, check the front & rear driveshafts for missing weights.

If you remove the transfer case - then what do you plan to do? Do you know exactly what you're looking for?

Have you tried putting the truck in 4WD? Does it do anything different? Does the vibration go away or get worse?

 

- transfer case and transmission oil change
- greased u joints look ok
- IF the carrier bearing is the center bearing on the drive shaft, the rubber looks ok but how do you tell if is good
- no weights missing only thing i saw was the rear u joint expansion joint is missing the grease nipple, must have broke off.
- I was going to bring it to a repair shop that specializes in that
- I put it in 4x4 and it is the same. seems to be worse at 80 km/h (50 mp/h)

 

what does the truck do if the diff oil is low or dirty ??? it wont vibrate right ?

 

any way to check what side bearing is out ?? rear left or right ??

 

thanks
