I install the gears on the rear differential on my 93 ckerokee country. i think that i didn't install my carrier bearing right or didn't adjust them correctly because NOW when i drive it it make a loud humming sound. Has anybody have this problem. or tell me what i did wrong. its a chrysler 8.25

 

i installed 4.56's and mine has the same hummmmming but i have posted before no one replied to mine either! i think is good question!

but ya i called where i got the ring pinion from and they said gear i ordered will make noise, cuz its a bigger gear and i did not buy the high end one! but i think i will be taken to my buddy when i switch the gear oil after its 500 miles break in!

good luck
