axel seal replacement
Hi Men
Looks like I need to make a decision about replacing (or NOT replacement) the seal in the front differential.
The truck's a 2003 1500 4.7L 4X4 (and bare in mind that I'm with it overseas...)
Some mechanics over here are recommending that since it's not a new truck that I should basically ignore it and just make sure to periodically top off the differential fluid and let it slowly leak.
Is this really such a major and expensive job back home? what do you Guys think? I really need some advice to make the decision. Thanks for any thoughts. Cheers

The front shouldn't be a whole lot different from the rear. It depends on which seal you're talking about, but they should both be a fairly easy and cheap fix.
the pinion seal on my rear diff was completely destroyed, it cost $40 for a new one from the dealer (Canadian money) and took me MAYBE 2 hours to change, and the ONLY reason it took me that long to change it was the excessive amount of time I spent just chillin' out under the truck, looking at things and daydreaming, finding other tools, and cleaning everything up.
I wouldn't imagine the front to be too much different. Remove the bolts from the companion flange, and slide the drive shaft back and out of the differential.
mark the bolt and companion flange with a punch so you can tighten the flange bolt to the exact same spot. Remove that bolt and slide out the yolk/flange assembly.
remove seal.
insert new seal.
reverse operation to reassemble.
That is the entire job roughly summed up.

Very helpful info and thanks! I unfortunately don't trust my own DIY skill to do something like this myself, but at least you've armed me with a pretty fair understanding of the task at hand should someone want to take me for a ride.
I just keep hearing that the problem is that the diff itself has to be properly "calibrated" if you will when the drive shaft it reinserted, and that this is what makes the whole procedure so complicated and time consuming. Your description sure does make a different impression.
Thanks again!
