Gears & Axles - Smoking rear axle bearings

I have gone through 3 rear axle shafts and bearings in the past two years. I had it replaced the first time ran it not even one summer and it was bad again. Replaced it for the second time had everything cleaned to the max entire rear cleaned out lasted about a summer and a half now it is bad again. Does anyone have any idea what could be wrong?

Factory rear or aftermarket?

Insufficient oil or improper oil in the rear end, perhaps?

It is just a factory rear and it is always the passanger side that goes never had an issue with drivers side

Does the passenger side tire wear more on the inside of the tread?

Sounds like the housing may be slightly bent, or you are letting the oil level get too low.

good to know thanks guys last things how often should I be adding gear oil and also I have a guy that wants to sell me a rear end but its a 4 channel will i have any issues since mine is a 3

Yes,you'll have issues ! A 3 channel can be converted to a 4 channel by using/swapping the 4 channel axles and backing plates into the 3 channel rearend. A 4 channel is not worth converting into a 3 channel because of the machining necessary to do on the housing and putting the reluctor onto the carrier.

Good to know I am glad I didn't buy it thanks guys

sounds like its time to spring for a new axle housing.
