D30 axle seals, how hard to replace?

I want to replace the badly leaking axle seals in my 95 XJ tomorrow. I have the replacements in hand, how hard of a job is this going to be? I can handle pulling the hub assembleys and axles, but I've never taken a diff apart before. The FSM shows a special tool to R&R the seals. Can I get away without it? Thanks.

Got a Torque wrench, Pry Bar, Wrenchs, Pliers, Socket wrench, and sockets, a new cover gasket or RTV, and a socket about the same OD as the seals? that's about all you'll need. not too hard, but you can screw the axle seals up real easy. once you tweak one, it'll leak. but you're not gonna learn until you dive in and screw a couple up anyway [img]/ubbthreads/images/graemlins/grin.gif[/img] It's not that hard. hardest part might be getting the hub assems out of the knuckle.

Yep, I've got all the tools in question, and more. I've had the hub assy's out before as well so I hope they come apart fairly easily. About the only thing I'm a little nervous about is pulling the ring and carrier out along with the rest of the works. It's been years since I did that. Thanks for the advice.

don't worry about pulling the Ring and Carrier out. just make sure you keep the left Bearing Cap on the left and the right on the right, and torque them back down to spec.

Easy easy stuff. As brent said make sure you keep the caps and races sperate and the caps going right direction, i usually mark em with a punch. As for putting seals back in i use a socket the right size to help drive em in.

Re: D30 axle seals, how hard to replace?

The hardest part is driving the new seals in. I just did it (again) this week. I used a socket with an extension on it, then slid a long pierce of metal conduit over the entension and out the opposite axle tube, then just line it up and smack the end of ther conduit, driving the seal into place. The sort side is easier, instead of the conduit, I just attatched a breaker bar to the socket and hit the end of the breaker bar. It helps to put the seals in the freezer first .

Just an update for all of you that offered advice. Everything went fine and no leaks so far. Everything came apart smoothly and went back together likewise. I stored the seals in the freezer for a day and poped em in with a 1 5/16" socket on a couple of long extentions. Worked like a charm. Thanks guys.
