I am chasing a vibration issue that I believe is coming from the rear end. It's more pronounced at speeds above 60mph. I like to cruise around 70 mph. When I'm driving alone, I can see the passenger seat back shaking and if I have a bottle of water in the cup holder, you can see the vibration in the water.
I have replaced the carrier bearing and U-joints I believe 2 years ago and had it balanced by the driveshaft shop. All the driveline components were replaced with Spicer stuff.
What I've been noticing lately is the rear end of the truck starts to bounce when I apply the brakes. I am wondering if the drums are out of round or have a balance issue. There is no steering wheel shimmy or pulsation in the brake pedal. Or something going on with the rear end.
I was thinking about taking the rear driveshaft off and running in with the front wheel drive. Could I bring the front end up to 70 mph?
Anyone know what the pinion nut torque suppose to be? Is the pinion a crush type collar? I'm wondering if it backed off slightly?
I need help on this as I have a 2000 mile round trip coming up in 2 weeks and hopefully I can figure this out. All the shops and mechanics I spoke with, don't really want to be bothered with this.
Oh yea, I put the truck on jackstands and drove up to 70 mph and the vibe was there. To eliminate the tires/rim, I took them off and put all the lugs back on....the vibe was still there.
I'm at wits end on this. I also took off the traction bars in order to isolate this issue. I do have the carrier shimmed down 1" (have it like that for years). I have played with shimming the carrier down, up and removing the shim with no difference in the vibration.
