Hi Guys, another short question:
I'm getting horrible vibrations, worst in third (When engine to driveshaft ratio is 1:1). Think it's the driveshaft (or rather the rear U-joint, seems not quite round and is missing a few needles). How do I find out what U-joint I need? I've heard that they like breaking suddenly if chosen too weak and my car weighs 5000 lbs. Can't seem to find a number on it either... It's a 1983 G20 van, the shaft seems straight though. I also got a new damper, so it can't be that.
And another question regarding this vehicle:
I'm getting pretty poor mileage out of it, but massive acceleration and early gearchanges. Think I might put a bigger rear gear in it. What's the biggest you can get that'll fit in a standard differential case?
Would appreciate any input. Thanks a lot,
MadMax
