Replacing Rear Axle Seal?

[TallTexan]

If I was going to spend any money on a stock diff, I would install TruTrac at the same time. Might as well fix both problems at the same time. I see a complete new axle can be bought for around $1200 for non locking axle. If I am going to spend 500 dollars for a fix I know will return, I will go for a complete fix.

While I haven't done it...this is how I think it's done???

Remove the wheel/tire assembly.
Remove brake caliper/rotor/etc.
Remove four bolts/retainer plate which hold the axle/bearing/seal.
Slide axle out.
Destroy seal/bearing to remove.
Install new axle/bearing/seal assembly "kit" (How much of a PITA this is, IDK??)
Re-install the four bolts/plate.
Re-install braking system.
Re-install wheel/tire assembly.
Install Axle Vent Mod

Top off diff fluid.

Someone correct if that is wrong somewhere.

There is a collar that is pressed on that holds the bearing. That has to be broken off before you can slide the bearing and seal off. The new collar will come with the seal and will have to be pressed back on to the axle. If your going to do it yourself I would replace the bearing also just for peace of mind. So you wont have to do it again for the bearing. And yes definately do the axle vent mod.My right rear axle had a little seepage and after I did the vent mod it seem to stop. My backing plate is still dry after I had wiped it off. I think my vent must have been plugged causing pressure to build up and forcing the oil out the seal. because now after 7k mi. Its still dry.

It's a lot easier if you have a press to get the bearing off. The bearing will get destroyed and will need replaced.

so the only parts i need to order from the dealer is the axle seal and the new bearing correct?

Here the P/N and price I got from the dealer.
Axle Seal P/N 43252-7S200 $38.15
Bearing P/N 40210-7S210 $75.44

Anything else?

No, you'll need the collar and the plate that has the studs on it as well.

On my old 04 I had the dealer do 4 seals before 62k...I wanted a new rearend on the 2nd one at 30k Something must have been wrong to blow 4 right? Well now they didn't fix the rear end and I decided to sell the truck because of it causing the seals to fail every 15k. Too bad Nissan can't stand by their products and just let their customers get screwed. And you wonder why people won't buy the titan again.

I picked up a CD-ROM manual off eBay. It's very detailed and worth the measly $10. Just a cheap copy on a disk though...

I can't post links yet, but it's Item number: 190220600397 (go to eBay.com and type in the item number in the search bar)
