axle shaft lenghts

ruger81 · Oct 4, 2011

87 dana 44 what side gets the longer shaft(29.75) and such side gets the (29.25). The reason im asking is because I can't keep my wheel seals in the rest from leaking and the guy at the axle co. Said it matters but I put the same length in that I took out the first time no luck.. I have done this three time. At like 87$ a time.

I forget which side is longer, but I've been having the same problem (leaky seals in an early XJ D44). Post up if you make any progress

Check to make sure your vent tube/hole isn't clogged. If the expanding air can't escape it may cause the seals to unseat.

Just remember it's the same as the Dana 30. Short shaft is on the driver's side and long shaft is on the passenger side.

If its coming out of the axle ends, that means the axle seals are toast. Unfortunately the seals are installed on the axle behind the press-on bushing. You gotta cut that off to replace the seal. Do the bearings while you are in there.

If it leaks from the pinion, just replace the pinion seal. Remove the pinion nut, pull the seal, replace the seal, install the nut. The torque is something crazy like 225 ft-lbs.

its possible that the sealing surface on the shaft is grooved and can no longer seal properly, even with new seals. but there seems to be a solution, speedi sleeves. there is a writeup here on them

Axles have 600done miles on them no grooves

I'd follow the previous advice first, and verify the vent isn't clogged. Assuming that isn't the problem, is there anything "non factory" about the cover or pinion angle that might be causing you to overfill it? I knew of someone who filled his on a steep incline which caused it to shed the extra lube until it reached it's "happy level" and stopped leaking.

The first thing I checked was the fluid level then the vent tube..
