Most Spridget rears howl a bit. They originally came straight off the
farm tractor and high speeds were not considered back then.
The 3.9s and 3.77s are considerably more quiet then the 4.2.
Swaping out the pumpkin is not a bad jod, pull the axles out a bit, undo
the drive shaft, unbolt the diff and make the swap.
I do have a "we tight" fix for noisy diffs though.
If it is noisey and you do not want to have it rebuilt, fill it with
cedar saw dust.
Yup! sawdust will quiet it right down and will not hurt it (much) over
the next 10 years or so.
Use cedar because it is a high oil content wood, NOT chips, just sawdust
mixed with new gear oil.
I did this years ago and that Sprite is still around and no diff noise
yet. The new owner knew about the sawdust and I did give him a spare
diff if he ever wanted to change it. Last time I saw him he said it was
fine. I sold that Sprite back in 89 and it had sawdust in the rear for a
few years before I sold it. He has never changed the oil either.
The sawdust is soft enough to not do any damage, thick enough to make
things quiet, and a whole lot cheaper then a new ring and pinion.
Hey if it's shot, what do you have to loose except a couple bucks for a
cedar board you have to cut up.
