Ok Randolph, we're devolving my serious vibration thread into another "Boathouse Ballbust". I declaire a cease fire, right now. :drink: |
Re: '99 Burb Vibration - I'm stumped!!!
OK but I still say any thing driveline out of whack enough to cause the vibe would've destructed itself in 75,000 miles
maybe it will tomorrow and you'll have your answer. :eek: :D |
Re: '99 Burb Vibration - I'm stumped!!!
My 93 and my 99 both did the same thing
took me a year, 2 sets of tires and wheels, 4 tire balance shops, 1 set of drums, 2 axles, posi unit, just to figure it out on the 93, then found the cure by coincidence one day, with a real sharp friend of mine helping me do it myself... fixed the 99 in 1 hour doing the same thing it's the rear brake drums the drums have to be balanced ON THE TRUCK using a strobe balancer, and using a drill with 5/16" drill bit, you drill multiple small holes 5/16 deep on the inside drum lip on the heavy side of the imbalance plane to zero balance the rotating ASSEMBLY, with the tires off, and ALL of the lug nuts in place, use the engine to get to the highest vibration point, and mark the strobe at that point. Have jackstands under the rear axle tubes to support the actual chassis weight under load that'll fix it. if it doesn't, it's the limited slip posi carrier out of balance, and there were a TON of them that were this way.. if your truck has the C6P option, it's one of those two scenarios, non C6P rear ends didn't do it.

Jim How do I know if I have a C6P rear end? It is a posi unit. I'd be inclined to think it's the rear end since I did replace the drums and it made zero difference, same vibration, same speeds, same magnitude. I would think different drums would change the vibration if they were the cause. Agree? Thanks for the input Jim. |

look for C6P option code on the RPO sticker in the glovebox...
