D30 Blew seal question..

hey, this past friday I blew my u-joint, and the seal on my passenger side D30... I have a d60 im gonna be putting in soon, and don't want to spend the $ to put the new seal/bearing in (since seal is non-servicable)..

If I replace the u-joint, and just dont use 4wd will my driving be ok? (on-road only)

it doesn;t bother me if 4wd wont work ANYMORE since i wont be using it until the new axles anyway...

but I`d like to drive it...

Re: D30 Blew seal question..

Is the front axle leaking fluid?

If it is, then the seal just outboard of the front axle disconnect is leaking. It's a $5 part that is a little screwy to install, but straight-forward.

If you blew a seal on the unit bearing at the wheel, the truck will be fine until the unit bearing gets full of crud and the bearing fails and the wheel locks down!

I am guessing since 4wd no longer works, either the axle seal mentioned above has failed and spun on the out shaft and is interfering with the shift motor, or the inner axle bearing at the shift motor croaked when the u-joint blew and is dragging prevent the shift collar from engaging. If the latter is the case you could trash the D30 diff gears and could cause you some problems driving around. If it's leaking fluid, just keep an eye on the level.
