Hi All,
Well I drove the 65 Chevy Grumman project van home yesterday . Wow... I didn't think it was going to make it .
There's a howling that's either from the trans or the diff . I can't tell which .
The noise is worse at lower speeds, like between 20-30 mph and is less once the truck gets going 40 or better . The noise is not as bad when backing off as it is when the truck is gaining speed . When on a flat road with little to no load the noise is gone .
There's some play in the pinion gear , but I've seen worse cases of excessive gear lash that didn't produce the noise this think makes.
Any ideas of what to check ? It almost sounds like a bad bearing in the trans . Has a bad trans bearing ever caused a howling noise?
I'm really starting to wish that I'd walked away from this nightmare .
Thanks again for all the support !
Oh yeah, 292 with a 4 speed and a front loading "pumpkin" type 1 ton diff.
