Axle and Pinion seal swap tomorrow: check my list please

Ok, I have done tons of searching and I think I have everything I need to do my front and rear pinion seals as well as my front and rear axle seals.

Here is the list of parts/tools I have:
-F&R axle seals and pinion seals(got from dealership, assume they are correct)
-1 1/8" socket for pinion nuts
-1 7/16" socket to use to press front axle seals into place plus a couple long extensions(from this writeup: Changing D30 Axle seals)
-black RTV(should I use red instead? not sure how hot axles get, but not thinking above 500 degrees black is rated for).
4 quarts of Amsoil 75w90 Severe Gear

I obviously have a fully stocked tool box with all the standard stuff in it. Ive got a torque wrench(up to 150ft. lbs) and a 3' breaker bar. Any other non-normal(like the big sockets listed above) tools I would need? Anything else I should have ahead of time? Anything else I should do while I am in there?

You'll need a 36mm(?) socket to remove the front axle nut.

im planning to just take out the 3 13mm bolts from the back of the hub and yank the whole unit like Stu(I think) shows in his write up. I guess I should have mentioned that.

You're pulling the front carrier to replace the inner axle shaft seals located inside the pumpkin?

yup. got one thats leaking badly so I am going to do both obviously once I open it up. Front pinion seal is also leaking so going to do that at the same time.

Rear pinion seal is leaking so doing that. Going to do the rear axle seals just because.

Jeep hasnt seen much maintenance by its prior owners so I am trying to get it back into shape.

You left off "a friend" you would have to have real long arms to hold\align and tap those seals in place---good luck on the project.

got my old man to help me with that.

He took the day off work to help me.

Here is how our conversation this morning went"

Dad: I took the day off work tomorrow to help you with your jeep.
Me: I thought we were working on it on Wednesday.
Dad: I can take Wednesday off too if I need to.


Man I wish I worked at a job that I could just say "hey, im not coming in today, see ya later" and still get a full paycheck.

Well, got the front axle seals done.

We hit a bunch of "while were in here" or "while we have it torn down this far" and only got the front seals done.

Drivers side front wheel bearing(unit bearing) was brand new(or close to brand new). Passenger side was toast(plus we had to beat it off the knuckle with a 10lb sledge to get the axle out) so we had to change that. Picked up a 36mm axle socket. No friggen way we are breaking that 36mm bolt loose(although we tried like hell with plenty of liquid wrench and about 15 minutes with a torch plus a 4' breaker bar) so off to the closest mechanic for some air gun action. 2 seconds and he broke it loose with a 600ft. lb. air gun and wouldnt take any money for it so I went and bought him a 6 pack and brought it back by.

Went to drive the seals back in and the 1 7/16" socket I bought from Sears fit into the seal, but as we tried to drive it in(and the seal needs to compress a little) the OD of the socket was to large. Shit, what are we going to do. Well it just so happens that the 36mm axle socket was a MUCH better fit than the 1 7/16" socket was and we drove the seals in. So for anybody doing this in the future, skip the 1 7/16" socket and just use a 36mm since it has actual use in other parts of the Jeep. I now own a 1 7/16" 3/4" drive socket plus a 1/2" to 3/4" adapter that I will most likely NEVER use again.

Went to try to break the nut loose on the pinion yoke and that was a no go. So I am going to take that to a shop and have them do it with air.

Got everything in the front end greased. There was just about zero grease in any of joints that need it. My old man just kept pumping on the grease gun and couldnt believe it. I think I owe him a new tube of grease.

Good news was the front brakes were just about brand new. Bad news was the jeep has wheel spacers on it since the wheels are the wrong back spacing. Oh well, I planned to get new wheels eventually anyway since I dont really care for the ones that are on it.

Overall a productive day although I only really got one project accomplished.
