I tried installing a set of GSP or GXP (spelling?) axles from Advance Auto and it was not fun.
The removal was somewhat easy maybe 5 out of a 10 scale. Jeesh that gear lube stinks

Just pulled the driver side to see how the whole process goes and then planned to pull the passenger side.
Went to install the new driver side axle and the outboard axle stub won't go into the hub no more than 1/2" or so. Even tried to force them in a little but no go. I took it out and used my calipers to measure and it seems the aftermarket axles are about .015 too big. The splines also appear to be slightly higher, as in more raised. The difference would be hard to show n a photo but clearly visible upon visual inspection. The diff. side went in fine.
Took these back, went to AutoZone and ordered a new (not rebuilt) set of Duralast brand axles. AZ matched AA price of 69.99 from 129.99, we'll see if they are any better when they show up on Wed. I hope they are not GSP/GXP just rebranded.
Anyone ever have this problem before?
