Trying to figure out if it's the tires needing balancing, or the front driveshaft needs balancing, or the front output bearing that is going to **** on the t-case is causing it.

Thanks for the input.

 

or mounts
cdl test w/o front shaft to eliminate that

 

You mean like the motor and tranny mounts? I replaced them all like 2 years ago from rock auto and I think they are already toast.

I didn't think those could cause vibration.

 

yep and yep.......2 years is a very short life expectancy,though

 

Is the vibration high frequency or low frequency? A driveshaft vibration would likely be a significantly higher frequency than a tire out of balance.

 

It feels bumpy. This issue started up like 2 months ago when my driveshaft exploded.

I've since rebuilt it and my buddy at a driveshaft shop said the balancing was OK. Thing is I kinda hit some big bumps so a number of things could be wrong all at the same time.

I'm replacing the front bearing on the t-case next week since there is play in it but its been like that forever and it didn't vibrate before.

 

Well they are cheap Chinese crap. That's probably what I deserve. I know better...

After I rebuild the case and double heck the shaft and tires I'll look at the mounts. I hated swapping those out last time.
