Re: Dana 53 rear axle... know anything?
Dana 53 is an orphan, only used in some years Willys trucks and FC's. You cannot buy lockers or
limited slips for it. Willys did put powerlock limited slips in some but they used an entirely different axle
housing. You can get bearings and seals for it but hard parts like gears, carriers, etc are not available.
The axle shafts are beefy but if I remember right they are 19 spline tapered. Normally what breaks are
the spider gears, and these are getting rare. Last set I had I sold for $75, were rough, and the buyer was
tickled to find any usable ones (he offered the money, I didn't set a price). They are between a 44 and
early 60 in strength as far as ring and pinion goes. Unless you are restoring it back to original, sell the
axle to someone who is or who needs parts and put something more common like a 44 under it. At
least you will be able to get parts. Just my opinion.
