T-Case Bearings

I have a slight amount of movement in the front and rear outputs of my LT230 T-Case. Most likely it's time for new bearings. Has anyone changed out just the input and output bearings? I can't afford a rebuilt T-case right now, but if it's feasable to install new bearings that is doable.

I searched the site and it seems that most rebuilds were after catostrophic failures... I'm hoping I can get away with minimal work.

Thanks for anyhelp you can prvide.

Output you can do in situ, at least in front.

Why do you think the input bearings are bad?

Also, it could just be that the nuts are loose giving the play.

I just had the front output done in mine, fixed the play in the shaft but not the vibration problem I'm having. It vibrates between 30-37 MPH regardless of gear...weird. Its an inexpensive repair worth trying.

Thanks guys!

I already printed the procedures to change the front bearing.

Ron, at the National Rally this year I started hearing a noise when slowing to a stop, it sorta sounds like a drill motor as it is slowing to a stop. I have this noise, and now at speed when coasting you can hear a rumble type noise, but while accelerating or when under compression, no noise. I pulled the rear 3rd member Saturday, all is tight there.

The rear output moves just slightly as does the front output. The rear output seal is bad and leaking oil into the e-brake drum too.

I need to suspend both axles and do some in gear tests in the garage, maybe this will help with the diagnostics.

I have a LR mechanic coming over this weekend for a second opinion, but knew I would get good feedback from here too...

Thanks again

Follow-up Post:

Ron, I just realized I said input and output in the 1st post, I meant outputs.

Outfield, you noise sounds like the diff in the case. If it was run low on oil (you said it leaked) that could have gone bad.

Roadsiderob is the true expert on these matters. I am just a hack who fixes LT230s on my table once in a while for fun.

After I go the old one [bearing] I took it to the bench grinder & ground down the outside a bit. Used it to set the new one.
