I found a D44 out of a 2004 Rubi but the guy who has it wants to sell the salvaged Jeep. Not part it out.

If I add a locker to the rear of my D35 will it hold up to the 33's or should I just get the 8.8?

Nick, 3.73 gears are very common in the 8.8......just keep looking for one with the right gears. Forget about the 4.10 geared one....

Nick, if you're going to regear (and I would), then it doesn't matter what 8.8 you get, since you're going to want to regear to 4.56 or so for your 33's.....

It would be a waste of money to buy the 8.8 with the 4.10, thinking you'll just regear the front to 4.10. It's not ideal for 33's, and if you're going to regear, get the optimal ratio. At this point, if you know you're going to regear, then just try to get the best deal on ANY late model 8.8. I got mine for $250. Locked.

I thought about regearing to 4.56 for the 33's. But when I found this 8.8 for $150 with 4.10's I thought that it might be enough.

I don't think you'll be happy with it with 4.10 gears. If you have anyone local who's running the same motor/trans/4.10s and 33" tires, ask them to take their rig for a drive and see what you think. Of course, a vehicle drives differently when offroad, so see if they'll let you wheel their rig as well. If the gearing is something you feel you can live with, then go for it. Otherwise you're looking at having to regear....

Remember, there is no RIGHT/WRONG, there is only ideal and less-than-ideal.

8.8 is a rear axle. You.have a d30 up front. Only real mods are welding the proper brackets and makeing sure the gearing matchs in front and rear axles.

You probably have a d35 in back if diff cover is semetrical. If it's oblong and the bottom bolt is offcenter you have the much stronger d44 And don't need the 8.8 upgrade.

As said above, the 8.8 is a rear axle. If you installed one up front, you wouldn't be able to steer.

4.10 is not a great choice for 33" tires with the 5-speed manual tranny, that ratio doesn't really restore the power lost by the larger tires. 4.56 is the better choice. I made the mistake many years ago of only regearing to 4.10 when I was running 33" tires after my more experienced wheeling friends recommended 4.56. Within a week or two, I was kicking myself for not having gone with 4.56. I was constantly having to downshift with the 4.10 gearing, 5th gear was not very useful after that 4.10 decision.

The factory gears the Rubicon to 4.10 but that is for 31" tires. To get the same performance with 33" tires the factory gives for 31" tires, you need 4.56.

The only time 4.10 is the best choice for 33" tires is when you have the 3-speed automatic used in 2002 and older TJs.

Unless your going 35s+ there's no need to replace the front.

I had a thread going "what the best front axle upgrade not 1 ton" that u can search. Dana 30 locked will handle 33s. 35s u need to truss and put some Cromolies in but I got couple buddies runnin 35s locked on stock d30. They just bring spare shafts from junkyards.

There is an 8.8 front axle, its in an F150. Its not a solid axle, its IFS so you can't use it.
