Diff oil smells so good…

Aaron W says:

Get your self a nice brass wire wheel and use that to get the old gasket
off. That’s what ive been doing for 15 years never had a problem yet.

Bronson Burch says:

Question. If the backlash is loose and makes the clicking noise when
coasting, how bad is that to the differential exactly?

Mike Spindor says:

Great video thanks.

TruckNewDriver says:

Nice video footage but on top of it very Professional job. Thanks

For a 2000 Jeep Grand Cherokee, you’ll likely be using hydraulic oil,
75W140 up front and for the rear, 80W90 for normal duty or 75W140 for heavy
duty. If your particular Jeep has a limited-slip rear differential (e.g.,
Trac-Lok), you’ll need to add a friction modifier to the fluid – we’ve had
good success with Lucas’ gear oil products, which are available as the oil
with the limited-slip additive already mixed in, as well as an additive for
other oils.

thank you, this was just what I needed. The text makes it much less
abrasive to watch than having to listen to somebody drone on.

OneSourceAutomotive says:

@djoneab One of our primary goals with this video series is showing how to
do the job correctly, as we see a lot of DIYed work at the shop (yes, OSA
is a real auto shop) that inspires concern. If you’re gonna do it yourself,
do it right! 😉

nothing like some slap bass while scrubbing off gasket coverings

ZuranMarine says:

What did u use to clean the gears????

jullien83 says:

Thanks for much for posting this video! so helpful

djoneab says:

IN THIS CLIP….. oh wait wrong vid. This is how it’s suppose to be done!!
I like!!

OddlyIncredible says:

Best bet is to get it checked, it could be a solenoid, a switch, issue with
the diff, there are just too many possibilities and not enough information.

Iridium242 says:

Great video.. very thorough easy to understand. Hope to see more in the

OneSourceAutomotive says:

Actually, we use captioning instead of narration so that folks that are
following along can pause the video and have the text still be there. It’s
easier to follow when doing the job. 🙂

OSDCrusher says:

Not for road use you don’t weld a diff

bhopperlinc says:

Great informative video! I just bought an ’85 chevy Scottsdale 4×4 and am
tuning it up. Was gonna change the diff fluid in front and rear. Didn’t
know there was fluid to change in the transfer case. Thanks for the video!

zach berg says:

Where did you get that drain plug tool?

connormkoren says:

Very helpful! Thank you. My 2000 Jeep GC’s front differential is leaking at
the very bottom of the seal, so I want to open it up, replace the fluid,
and re-seal the cover. This video definitely helped out, but I’m just
curious, what specific kind of oil and additives should I use to refill it?
Please, let me know. Thanks.

OneSourceAutomotive says:

Some differentials use an actual gasket, and others use sealant. The
sealants we prefer to use are specially formuated silicone and RTV rubbers
intended for use as gasket material, and most of these are “apply bead,
torque down, done,” as the formulation for gasket RTVs is often self-curing
even when exposed to other chemicals. Toyota’s FIPG (Form-In-Place Gasket),
for example, can skin over in an hour and fully set in 24h while submerged
in engine oil.

I love this video,i do my and replace the seal,save time & $.

For the mentally challenged it is “no special tools required.” Kind of a
given. A lift is a nice thing to use IF you have one, if not run it up on
ramps. Now get your head out of your ass.

heavymechanic2 says:

I think this is one of the most neglected services there is on a vehicle,
great tutorial. I used to do mine every two years before I was introduced
to Amsoil synthetic oil which is recommended every 50-100K miles.

B ikerBoy says:

Thanks a lot I’ll do it on my pickup asap 😉

heavymechanic2 says:

Be sure to only lightly torque the plug in your transfer case or you will
regret it later. It will be stuck forever or possibly crack the case. Just
a tip.
