I have an 87 iroc with the 9 bolt, are the axles for a 10 bolt the same as for the 9? If they are where can i get them? If they are not the same where can i get axles for the 9 bolt? and finally can the axles be changed with out taking the ring and pinion apart, and is there some where i can find an out line of the procedure for doing so? Thanks for any help.

 

Nothing internal is interchangable between a 9 bolt and a 10 bolt. The only thing these 2 diffs have in common are the external mounts.

9 bolt axles can be removed by simply unbolting the 4 bolts that hold it to the end of the housing. You then just pull the axle out similar to a ford 9"

To my knowledge there are no aftermarket replacement axles available for the 9 bolt.

I have one stock axle if you need it....

Already sold the other one....

 

I was wondering because sooner or later i want to replace my axles, but i want to do both, i haven't broken one or anything, but thanks anyway

 

FYI: Moser Engineering makes replacement axles for the Austrailian 9 bolt. I emailed them yesterday and they quoted $295/pair, shipped two days after you place the order. Good Luck!
