I recently got my rear diff rebuilt with a yukon ring and pinion & a detroit true truc, I got the driveshaft balanced with new u-joints, and my tires rotated and balanced. I was still getting this funky vibration.
Long story short, I just got back from Thrash Driveshafts and they hooked me up with a new pinion yoke, and showed me how the old one was worn out. They also threw in a fresh spicer u-joint.
Now it rides like glass, for the most part, except for a little vibration at like 70 mph. I think it might be due to an unbalanced Drum on the Rear Brakes that I got at O'Reilly's. I bought 2 brand new Wagner drums and 1 was obviously balanced, with a weight welded to to the outside wall just like stock. The other had no weights, and wasn't balanced. When I tried returning it for the correct one, the guy was trying to tell me that drums don't get balanced, ever. I asked him who told him that b/c he doesn't know what he is talking about... (Correct me if I'm wrong but I'm about 99.9% positive that the weights on the outside wall of the drum are to balance them, and that they are not cast perfectly, just like wheels and tires need to be balanced)
He proceeded to tell me that they perfectly cast the drum when it's manufactured and it didn't need balancing... :rofl2: Any ways, since they ordered the wrong drums like 3 times, I just stuck with the Drums I had already bought; 1 balanced, 1 unbalanced
Could that 1 unbalanced drum cause a little vibration at 70 mph or what?
The only weird thing is that there's no DUST COVER on the new pinion yoke.
Check out the 1st pic :wtf:
The 2nd pic shows how the pionion yoke used to be with the original dust cover.
Is this bad? :think:
