The axle seal is a bigger job than you want to pay somebody else to do! You can do it, I'm sure the only reason you say "no so much
" is just a lack of experience,,,, Now's the time to get some
First thing is, the seal you see at the end of the tube is Not the axle seal. The seal is actually inside
at the other end of the tube next to the center section. You're Really going to get some driveline experience here
You have to pull both axles, drain & remove the diff cover, unbolt the caps and take the ring gear & carrier out. Then, you can get at the seals (how bad did you say it was leakin' ?
Also, there are these expensive Knuckle Seals in the hubs that cost as much as the U-Joints (and yes, once you've got those in your hand you might as well replace them) and if they've been in there a while, you're going to destroy them getting them out.
So, you need U-joints, Knuckle seals, dust seals (the things that are actually at the end of the tube you see), O-Rings, might as well put needle brgs in the hubs (they're cheap), diff fluid, a Couple of thousand
dollar job at the dealership (how bad's that leak?)
The TC not too bad to get out (Top bolt can drive you crazy
) good time to inspect the rest of the U-joints in the front driveline as well as that ball & spring in the cardan joint. Splitting the case is pretty straight forward, you need some big sockets to get the yolks off, lots of little bolts hold it together (Again, leaking real bad is it ?)
Curing the leaks you describe is going to take some effort, I'm sure you can do it, just have to weigh the job vs the amount of fluid you have to keep putting back in....
