Question
1500j
2001 Suburaban 3.73 rear end towing package LT. No lift factory everything. Just put new tires on it as well. 212,000 miles.
Ive had a 70 MPH somewhat harmonic vibration that has been happening the past two months. Its comes on @ 65 peaks @ 70 and is gone by 74mph.
Ive done many things. I have had the rear U Joint replaced twice. Once by me and once after I took it to a driveshaft balance shop.
HERE IS WHAT IS INTERESTING!
If I take the rear driveshaft out plug the transfer case and run the Suburban as a Front Wheel Drive truck in 4x4 the vibration does not occur. It drives smooth as silk when in 4x4 with ONLY THE FRONT WHEELS PULLING the suburban.
Any guesses as to what it is???? Its killing me. I cannot figure it out.
I just had the driveshaft balanced and they put a new Spicer u joint in while they did it. They said the front one is in very good shape.
Thanks, Im new here so if this needs to be posted elsewhere. Let me know
