I just bought a really beat 89 cherokee lifted 6.5in on newer 33in mud tires. The rear end is a 8.25 that growls really badly during deceleration. What would be an easy swap (dont want to screw with gearing if i dont have to!) I wanna wheel it soon however i dont wanna run the risk of it blowing up on a trail.

 

another 29 spline 8.25 would be a good replacement

 

x2. what is your current ratio?
another option is to buy an already geared 4.10 hpd30 off CL or NAXJA and buy a junk yard 4.10 limited slip 8.8
killer setup especially if you got stick shift and are ready to commit to the ultimate upgrades

 

No idea on ratios i paid $500 for it lol just wabt to go to a junk yard pull a new axle slap it in and go

 

Truck is automatic.

 

Any automatic should have the same gears. You could swap in another 8.25, a Dana 44 or if you wanted to gamble a bit you can go to a Dana 35(most common). The 8.25 is longer so if you go to a Dana 35 you might need a longer drive shaft.

Do you know why it's howling though? It could be a number of things that might not need replacing. Is it locked? Do you have a slip yoke eliminator on your transfer case?

 

No sye that i can see and the yoke has a lot of side to side play
