I have two problems with my 97 Dodge 2500 CTD.
How serious a problem is a leaking rear pinion seal and a leaking transfer case seal?
Are these expensive fixes?

 

I know the tranfer case seal is an easy fix- remove the skid plate and front axle. Then the seal.

Both are easy fixes. You need a service manual if you don't already have one.

 

Big Jimmy they would both be even easyer fixes if he left the front axle in place and only removed the drive shaft

 

Good thing I'm not in politics....my career would be over! I meant drive shaft, not the axle as that Big Jimmy guy said... (who is that guy anyway??)

If you have a rear pinion seal leak, you may need to look at the rear end as well. Typically the seals only go if there is bearing clearance and not enough pre-load on the pinion bearings. You might replace the seal and in 4-5 months will have to do it again. If you are doing the pinion seal, take the rear pan off the diff and take a look at the gears, oil etc for wear or wear metal in the bottom. You need to shim the pinion assembly for proper pre-load so its not as easy as making the nut tighter.

 

If its the rear axle and the rear seal on the T-case I'd check the carrier bearin on the driveshaft while ur at it.
