Differential Pinion Seal Replacement DIY - Done! DL it here!

Alright, it is finally done.

20 pages, 44 steps, 34 pictures, and 16 pages scanned from the helms service manual.

Below is the link to the differential removal DIY for those needing to replace their differential pinion seal - or anything else that requires removal of the differential.

I hope it is comprehensive enough.

Let me know if something is wrong, hard to understand, or just what you think of it in general.

Download it here (right click - save as).

Thanks,

James

Are you leaking differential fluid?

I knew my differential pinion seal was busted because I had drops of diff. fluid on my garage floor in the morning. The differential fluid in our car is gear oil. It is yellow, somewhat thick, and smells pretty bad.

Nope, no fluid leaks at all-except for water when the A/C is on...

I hope I never need it, but good to know it's here if I do. DEFINATELY NEEDS TO GO IN THE DIY SECTION!!!

James - thanks for the extensive write-up. Some questions:

1) What was the most difficult repair procedure you did before this one & how did this compare to it in difficulty?

2) Did any of the steps require a second person?

3) You said that disconnecting the upper coolant hose was very difficult. Would it be possible to cut this hose instead & replace it (would this make it any easier)?

4) Are there any other items you would suggest replacing with the differential out?

5) If you were to do it again, what would you do differently?

Thanks again.

Hey Oldacura,

Sorry for not replying sooner, I actually have a sticky note on my keyboard to remind me to respond to your questions in the other thread

So here are the answers:

1) I'd have to say the most difficult repair I did before this was probably replacing my brake pads - not very complex However, I did have help from someone who knew what they were doing. They hadn't done any work on Legends specifically, but work on cars in general. I probably would have been able to do it myself, but it would have taken longer.

2) Yes - when I was putting the differential shaft back in I needed someone to turn one of the axles to make the gears in the differential turn so the teeth on the shaft would line up inside the differential. (See step 29.b.i)

3) Yes, you could just cut this hose if you wanted. It would make taking it out easier. Once the differential is out you should be able to unclip it from the engine side pretty easily and just replace it. It still might give you some trouble when you put the differential back in as you'll have to attach the hose to the engine side first.

4) Hmmm, not that I can think of off the top of my head. I listed pretty much every part that the service manual tells you to replace when removing, so I think you should be good.

5) Probably would have drained the coolant instead of trying to plug the holes - that made a huge mess.

Let me know if you have any questions. Also, if you want to have my phone number around for when you do the job incase you have any questions, I'd be happy to give it to you.

-James

James - thanks for the reply.

I'm not especially mechanically inclined with my car. To date, I have replaced the radiator & hoses, the brake master cylinder & the brake pads. Neither of these was very difficult. I've found that if you're just willing to tackle a job, their not too bad.

Several people have talked about how difficult this job is and especially how difficult it was to disconnect the upper coolant hose.

I might have a hard time finding someone to help me with the job but I have 2 cars so if it takes a while to finish, so what.

My diff was leaking but I put in Lucas Oil Stabilizer and the leak stopped (temporarily). I'll file away your DYI so I can tackle this in the future.

Well, those jobs are more than I had previously done, so I think you'll be fine.

Good luck and let me know if you have any questions.

Just wanted to say nice write up and give it a bump to the top. I'm in the process of replacing my oil pan and the pics and part numbers are nice to have.
If I may make a suggestion or two: I would mention in your write-up that the transmission should be in park or neutral. Another suggestion would be to include current prices for each part number listed. (would also be useful to list the weight of the diff so people reading your tech article could judge if a second person is really needed or not)

Glad it was of some help...

I don't think the transmission HAS to be in park or neutral... Even if the car was in gear you should be able to pull the pinion shaft out, although it might be a little more difficult. Weights might help, but really the only one that is heavy is the differential itself... We used a jack to give it support as we unbolted things. It's about 50 lbs, which isn't too bad except for when you are trying to hold it up for 2-3 minutes under the car while your buddy attempts to put the bolts in

I didn't buy one. I used one of the 3 bolts that holds on the intermediate shaft and one of the huge washers under the hood that goes on the top of the suspension.

Have you read the instructions yet?
