Front right axle seal part number and tools

My front right axle seal is leaking and I will be replacing it.


I am not sure which part it is. I think its 9031147026

Anyone know for sure?

Also any exotic tools besides slide hammer bearing puller?
Also how hard it getting the CV out?
Thanks in advance

 

90311-47026. You got the right one.

Not sure about tools or the exact process. @Texoma may know, although he normally doesn’t change those with the gear jobs he does.

With my limited guessing, I would assume use a seal puller to get it out and then a large socket or seal driver to hammer it in straight and then stop at the same spot that the old one was at. Take a few pics of the old one for reference.

 

Thanks.
Yeah I was thinking of using the PVC pipe to hit it in

Good idea on taking the pics for ref on the depth. there is supposed to be a lip but I will take the pics anyway.

 

I actually have one of those because I just bought it for my regear but didn’t need it. I don’t think it had a lip but I can confirm. The left side is for sure installed to a specific depth.

I’m not exactly sure on removing the CV, on past vehicles I used a pry bar. On the Tacoma specifically, remove the two lower steering knuckle bolts so that you can swing the brakes/steering knuckle away from the diff which lets you get the diff end of the CV out and moved out of the way without having to disassemble the stub shaft from the unit bearing or tear down the brakes or anything like that.

 

No lip on mine. I never did confirm it was the right seal in the diff but it was the only option I ever found on the parts diagrams. Pretty sure it’s right.

This is what you're describing. Thanks for the info.


This is the lip I am talking about. Maybe this video isn't a tacoma.
its at 4:22

 

BTW: $4 National P/N 710595 interchanges with the OEM part: https://www.rockauto.com/en/moreinfo.php?pk=2480322&cc=3441741&pt=1860&jsn=11

A screwdriver is enough to pry the old seal out. Make sure the seal seating surface in the diff housing is free of rust. Sand it smooth with sand paper if you see rust. Put some grease or diff oil on the seal to prevent tearing as you drive it in. It's difficult to get the seal to go in square. I used a seal driver, but instead of hammering on the handle, I hammered on the disc portion at different spots to get the seal to go in square.

No need for slide hammer or bearing puller, unless you're replacing the ball bearing in the diff. The CV axle needs a pry bar to pop free from it's spring clip. Once popped free, turn the pry bar around and hammer along the notches on the CV joint cup.

 

Bought the toyota one at 5x price. comments everywhere said it was necessary. not sure.

I am going to pass by autozone so I will rent the puller and maybe a seal driver

 

^The Toyota seal leaked, so you buy the exact same part and expect a different outcome?

Again, what is the puller for? Seal driver is very helpful.

 

Maybe I went through some headlight deep mud.....

The puller is free to "rent"

Do you know if I need the toyota

$26 75w-90 Synthetic Gear Lube - 1 Quart (Pack of 2)

75w-90 GL5 from toyota or mobile 1 works?

 

^Then make sure the front diff breather isn't clogged. Might be the root cause of the leak.

Any major brand 75W90 will be fine. In my experience Pennzoil/Shell/Quaker State (same mfr) smells a bit less horrid than the other brands.

 

Eh, not like they leak often. OEM seals are usually better quality than anything aftermarket. *usually, not always*

 

Whatever gear oil you want to use is fine as long as it’s GL5.

 

I looked at it. doesn't appear muddy
Should I just hit it with water?
Can I just pull the top off?

 

^Remove the breather from the hose and make sure air can flow out of it.

 

Exact seal depth is super important.

 

After replacing my front CV axles and differential seals, my passenger side axle continues to leak after installing a second seal.

Now I am wondering if my fully seating of the seal to the base of the differential opening is the culprit in this gear lube continual dripping a second time.

the second seal is a NAPA PN: NOS 18478, which they show as being different than the PN for the driver side.

Any insight is appreciated as I’d like to only be doing this a third time.

thanks,

Mike

 

Yes, redo it. If you install it too far which is easy to do, then the seal surface of the CV won’t reach the seal.

 

Thanks so much for quickly confirming this for me.

I’m whipped today after the 2nd R&R of axle and seal, so tomorrow I’ll dive in again and reposition the seal.

now that I think about it more carefully, I did see a small amount of shiny surface exposed on the inner surface after bottoming out the new seal. Though5 it was a little odd but I did wipe the inner surface in preparation for the new seal insertion.

thanks,

Mike

 

Resolved the leak on the passenger side by placing the seal just flush with the face of the differential opening.

This little tidbit, despite being published in the shop manual, goes against traditional convention of bottoming out oil and grease seals in their openings.
