I have 132 miles on my Cat 400 4x4 auto and I just noticed the right rear axle seal was leaking ,I don't feel like dropping it off at the dealer for a week for a seal .
I'm a auto mechanic have been for 15 years ,my question is ,is the seal easy to replace ? can I just pull the axle out without having to buy a repair Manuel ?
My other question is what kind of rear end fluid ? The closest Cat dealer is about a one hour drive .

Thanks for any help or advice Jwoods

 

My dads had the same axle leak except with 5 miles oin it. You are better off letting the dealer doing the work because if somethimg bad happen it is the dealers fault and the job itself is very tough. Hope this helps!

 

the same one went out on mine as well. it is not that hard of a job to replace it. what you will need to do is pull the cv out. what i did was take the starr head bolts that holds the rear diff housing on to the diff. once that was out i could easyly pull the seal out. you might not have to do that, but i foud it easyer to go ahead and unbolt it. once i put the new seal in i put some permeiaseal (bad spelling) gasket maker around the diff and bolted everthing back up. you use 80-90 hypoid gear oil. it holds 8.5 oz hope this helps

 

You know it's funny. I don't remember having these kind of problems out of my Honda 450's.

 

Thanks maximus I'll give it a try ,I'm going to order the seal tomorrow .
How long of a job was it ? I was just wondering if I can get it don on my lunch brake, I get an hour.

 

The same problem on mine wondering where you ordered the seal from also busted the rubber boot on the cv and wondered if you have any idea on where to find one of thoise I live in BFE and dont have a near by dealer and dont ever have time to go find one

 

I don't know where he got his but you can get them here or here.The second place all prices are in Canadian.
