Well, Maybe I made a mistake. I DID replace and rebuild the Dana 35. Put in a used drive shaft and cured the biggest part of the problem Still shakes at 60-70. Found that the drive shaft where it goes into the tranny is loose. I'll do the bushing next. Any idea what the part number my be? By the way, if you have a DS built, make sure the maker can BALANCE it!

Well guys, I've almost done it all. Replaced u-joints, ring & pinion, axle bearings and brake shoes. I have had three mechanics inspect the noise. Yesterday, had a new drive shaft made and the roar, vibration & whine are still there. Found a junk yard and ordered new differential and drive shaft. Is there ANYTHING else I can buy to add to the already $1,500.00 spent?

Forgot to mention, my Comanche is 2 WD. I also retired it on Friday - still vibrates. I will look up Spicer (?) U loins and install them. I'll get back to you guys. ALL help is appreciated. Slimjater

I forgot to mention that the U joints are tight. Transmission mout looks good and solid. Put jack under tailshaft and the whole truck lifted up. I would look up "Death Wobble" if I knew how to search on this forum. Any help on searching.

When my 1988 Comanche reaches 57.5 MPH a vibration and noise comes from underneath. It vibrates my seat. At 70 MPH it runs smoothe with no noise or vibration. This is something that does not happen all the time. BTW there is NO steering wheel movement. ANY suggestions would be appreciated. My first Comanche so I am clueless.
