In this video we visit East Coast Gear Supply (ECGS) in Louisburg, North Carolina to show you how to regear and rebuild your Toyota 8″ rear differential (3rd member). Chase Perry, the CEO of the company does all the work and explanation of the process.

There was a guy that reported his pinion shaft threads got damaged by not unstaking the nut before removing it. At playtime 14:38, Chase says there's no need to unstake the nut before removing it with a 30mm socket. To play it safe so this doesn't happen to you, I would unstake the nut before removing it. This is the toolset I bought to stake and unstake nuts: https://amzn.to/3j9AnPD

Reno's Garage says:

this video is exactly what i needed, i feel confident going into this now, thanks

ZPBeats says:

I did not unstake my pinion nut and it really messed up the threads on the way out and turned a one-day job into a multi-day job. I would have to recommend unstaking the pinion nut first before undoing it. Thank you for the video though tons of good info for a noob like me.

Darek Peterson says:

Can you provide the part numbers for the bearings?

Keggy says:

This is a great video.
Diffs are one of the very few things I've never gotten into on a vehicle just because I didn't fully understand setting preload/backlash, but this definitely helped a lot.

Bob C says:

Ok, so on a stock toyota rear diff he's recommending 75w140 gear oil? Just making sure I heard that right.

Ty Wheeler says:

Translation: hire these guys to rebuild your diff.

Time-Trvlr says:

I own a 07 FJ and it has the 8” dif like in this episode. Typical for them to fail at 70k miles, ECGS provides a exchange rebuilt for them. At 130k miles I once again had to buy a ECGS rebuilt. If you own a vehicle with this 8” dif I can attest that its from shock to the gears (spinning free then hit traction) that will break them no matter how many miles is on your vehicle. If I ever need a replacement ECGS has my business.

John Tetreault says:

Or… Just send it off to ECGS and know it'll be done right.

R Thomas says:

Great tip at the 16:35 mark for pulling the pinion seal. Hadn’t seen that before. Also interesting to hear he runs 85w – 140 gear oil. My understanding was both front/rear diffs called for 75W-90. Guess it’s just personal preference.

R Thomas says:

Starting out right around the 6:46 mark in the video when he flips the Diff over to show what’s happening when The actuator motor is locking and unlocking the diff he is pushing in and pulling out that part that has the fork part on it(sorry not sure exactly what he called it) when he pulls it out he says the Diff is unlocked, when he pushes it in he says the diff Is locked. On my third member I am not able to push that part in if I put a pretty good amount of force on it I can get that part to start pushing in but can’t get it to lock in position. Any idea what could be causing this? It is currently in the unlocked position but I am not able to push it in like he is in the video. It looks to me like he is not using very much force to push that in and sometimes just tapping it in with the side of his hand. On mine I am having to push it in pretty hard to even get it to start sliding towards the locked position. Thanks for any help you can give me on this.

Tim Garner says:

I had ECGS do my 3rd member last year on my 2002 4 runner. I have to say they do wonderful work on these vehicles. My 4 runner runs quite and smooth. Think I will do another 300k on this 3rd member and then i will send it back to have them touch it up. Thanks again ECGS, You people will always get my business.

sederick coxson says:

To find carrier preload is Total preload – pinion preload then multiply that by the gear ratio…. For instantc 10 inchlb preload and you install carrier and you spin pinion with carrier installed and you have 20 inch lbs with unit assembled and you have a 3.41 gear ratio… Itll be 20 minus your 10. Multiply that 10 by the hear ratio and you habe 34 inch lbs carrier preload….. How i do it hasmt failed me in years

sederick coxson says:

I always pack seal on diff builds and pack the lip with grease keeps em from burning up while seating to mating surface…And its wise to put a little anti seizer on face of nut to prevent galking when tightenin to make it easier tightenin pinion nut
