rear axle swap questions
on a c8.25 is it worth going from 27spline axles to 29 spline? the 27's are 3 1/2 inches longer, so does that matter? i have a open carrier in the rear right now and i was going to try to find a limited to slip to swap out with it. can i get a limited slip set up for 29 spline axles and just swap the 2 spider gears that the axles go into for the 27 spline axles? i am wondering this because one of the spider gears in my open carrier broke because i had to beat the center pin out and it was stuck on one. if i can swap them out it will give me the pieces i need later to put 29 spline axles in.

Do you hear banjos?
How big of a tire are you looking to run. A 27 spline 8.25 is not much weaker than a 29 spline. Two spline is not that big of a difference. Unless you are going to go big, in which case the 29 would prolly be too small anyway. If you are just looking for 31-33s, IMHO you'd be ok.

Where are you getting this info? IIRC, 27 & 29 splines are the same width, since they both come on XJs. If the 29 axle you are looking at is a different length, it could be out of a FS truck, and not an XJ. You would have to change the carrier as well, in order to put 29 spline shafts in your 27 spline housing. I have 0 experience with the 8.25 axles, so IDK if that will even work.

i went ahead and changed the carrier and axles to 29 spline today and it was a straight forward swap. i got everything i needed at PULL N PAY for $113 out the door.

now you gotta pay to have it installed too... to pay someone to do that you may as well go back and buy a whole axle and you still would come out better... lol

if its more that $98 to have the carrier and stuff installed just buy a complete axle assembly and then you'll have extra shafts for when you break them and you can either keep or sell the carrier
