Sorry guys.. I have a 91 jeep cherokee xj limited and will need to replace the gears in my d35 and d30. I've decided to regear to 4.11 because of my larger tires 31's. Will I need to replace the carrier or just buy the new gears?

 

what size motor do you have... If you have 3.55 gears you really dont need to re-gear to have adequate power

 

you should take the money and get a stronger rear axle, honestly...you can get a stock 8.25 axle with 3.55 or 4.10 gears for the same price as gears/rebuild kit and I know plenty of people that wheel up to 34's on 3.55 gears with no issue whatsoever.....but not on a 35

 

The engine is a freshly rebuilt 4.0.

 

how can I identify a stock 8.25 axle with 4.10 gears. I live in Puerto Rico and it's pretty hilly. Kinda like West Virginia terrain..

 

Here's the pumpkins....although the 8.25 should have a distinct flat bottom



4.10's came in the 4 cylinder and up country editions of early 90's xj's if you get lucky and you look at the diff there will still be a metal tag attatched to on of the bolts with the ratio on it

 

Thanks for the help guys..will look into it. If I opt to regear the d35, will i need a new carrier?

 

Yes, carrier break is 3:73- you could just take a carrier out of a V8 zj and use it, but once again I would not recommend keeping it let alone throwing money into it to regear it.

 

Not true... a Dana 35's stock carrier with 3.55's will except any gears numerically higher (4.10, 4.56, etc). So if you have 3.07's, you would need a different carrier. The Dana 30 on the otherhand will need a different carrier if it has stock 3.55's. But in my opinion if you are going to stay with 31" tires there would be no problem re-gearing to 4.10's.

 

Did not know that, learn somethin new every day!

 

I just didn't want the op to be confused.

 

Thanks Guys! I believe the 8.25 option might be more cost effective but will not rule out anything. We use the vehicle mainly for dd and trips to the beach and rivers. Nothing too extreme yet..

 

they are now offering 4.88's for the 8.25 so you can get pretty deep gears....especially if you aren't doing anything crazy yet, just try to get a 29 spline 8.25 (97+) basically on par with 44's depending on which snob you talk to. so with the stronger rear you can save time/money if you want to go crazy
