Bought a new Jeep over the weekend the guy had a 4.56 gears put in the front axle but didn't get around to putting them in the rear I the front drive shaft has been taken out. I was wondering if the 4.56 gears is to much for the Jeep it has an auto trans with 265 75 16 tires on it. He gave the gears to put in the rear and all new bearings and seals.

those gears seem like overkill for that size of tire

He is right ^^^^ But 35" tires would solve the problem!

What would be the gear I could run? The rear still has the stock gears in it. But Idk the ratio of the stock gears

most likely 3:55s.

go to this link, on the left side of the page under "Your Vehicle" theres a link for "equipment listing" click that and put your vin in the vin box:

If I put the stock gears back in the front will that work? I'm just gonna run the tires that's on it or put a set 31x10.50x15 on it when I get a different set of wheels

You can go ahead and put the 4.56 gears in and then get 285/75/16s which would be 33s when you buy new tires. 4.56 gears are perfect for 33s.

If I run 33s I will have to put another lift under it and I don't wanna trim the fenders I'm kinda on tight budget. If put the 3.55s back in the front axle will them be ok to run 31x10.50x15?

I have been running 31x10.50s on my stock 3.55 gears for a year and a half, it isn't ideal but it works.

3.55 and 31 will still be under geared IMO. I ran that and constantly had to keep it in third on any hill as overdrive is practically useless. Also had issues with the tranny getting hot. Youre better off saving some dough and getting the rearend geared and trimming the fenders if you get 33's.

Been running them for 4 or 5 yrs now, no problems at all under any conditions, but it is a little down on power from the stock tire size.
