99 runner 4x4 at. So I inspected the drive shaft am I able to repair the double cardon? I replaced the rear u joint and I still have vibration around 65mph and while coasting. The slip joint seemed ok and I greased it and the joints. What should I do? I heard you cannot fix the ujoints next the card on is this correct?

 

also check your T/C output and your rear pinion for play

 

they look like they have play but not sure and if play in them replace the bearings? I had the same problem with my 92 runner and where would I buy the case output bearing and rear diff input bearing? And can I replace the cardon joints with the same u joint I got for the rear at autozone? I know there are many many many threads about drive shaft wobble but everyone's are different it's fine from 0 to 50mph on and off gas and coasting in neutral but above 50mph I feel it most at 65 or 70 but at 85 it's gone til I let off gas and slight rumble for a second and its all smooth but at 65thru85 on freeway in neutral pure nonstop rumble and downhill in neutral is the same way at 60ish when I replaced rear joint the joint needles were pure rusted powder and once installed smoother then it was I couldn't go above 45 without it rumbling

 

well to let everyone know for an update: driveshaft bent and double cardone joint is worn out and transmission mount is shot as well automotix.com has a driveshaft for about 100 used with warranty

 

I was gonna mention the possibility of a bent shaft. Sounds like you gotit covered. Good Luck!

 

Forget that I'm searching and then try to respond to an old post...

Driveshaft and pinion angles matter. The set up has to be very close to these 2. When I lifted my truck I had probs, solved with proper pinion angle.

 

My last cure. 6 degree shims.
