Teague242 Well these must be long worn out then. Almost at 100k miles.

Will try the oil and see what happens, if not Ill start replacing things!

Thanks for clearing this up for me!

Yes indeed, the clutch plates in a Tracloc LSD due indeed eventually wear out. A commonly referenced point for that to happen is somewhere around 45-50k miles.

I will try that this weekend! If it has what would be considered clutch plates inside of the carrier, does that mean that it's possible for it to wear out?

Teague242 Would using a diff lube without the additive keep the LS from functioning? I used the cheap stuff when my diff was leaking constantly, but as long as I had the jeep the LS function never worked. Didn't know it had it until I looked at the carrier last week.

How would you go about fixing that?

Jerry Bransford Absolutely fine.

adkjoe since we are on the subject, is it OK to use the Valvoline 80w-90 oil that says "limited slip" on the bottle in a differential that DOES NOT have a limited slip? I would assume it would be fine right?

Jaxon1023 Thanks Jerry

Jerry Bransford Open carriers don't require a friction modifier. Most gear lubes contain that additive which is fine for both open and LSD equipped carriers.

Jaxon1023 My dana 35 is a tracloc but when regearing I'm using an open carrier. Since it came stock with a tracloc is my dana 30 a tracloc also or will it be open? Open doesn't require a friction modifier correct?

adkjoe good because I'd rather not spend $60 to change my diff fluid unless it really makes that much of a difference.

Definitely.

adkjoe I mean I try and change it every 12-15k and if I go through water crossings. So should the advanced auto brand regular 80w-90 be fine then?
05-19-2013 09:36 AM
Tdog02 Gear oil is not that big of a deal IMO. You need the friction modifier for limited slip but otherwise no. If its changed regularly then the brand doesn't matter much. Keep in mind most people never change the diff lube. I had several "mechanic" say its not necessary. I disagree, but I believe in preventing problems through routine maintenance. Just my 2 cents, I haven't need the extra benefits of the synthetics.
05-19-2013 09:09 AM
adkjoe I do not have a limited slip just a regular 30/35 in a 2006 tj
05-19-2013 09:00 AM
ken78744 If you have limited slip differencial in the rear then yes, because if you put that cheap CRAP in it will ruin your carrier because of no friction modifiers in it like the expensive ones do, or spend the $4.99 and then another $12 for the added friction modifier...

Gear oil

Company loyalty aside does it really make a difference if I use advanced auto brand 80w-90 gear oil in my diffs at 5.99 a bottle or do I really need to pay 10-20 dollars a bottle for mobile 1, valvoline or synthetic gear lube? Just looking for an honest answer how much of a difference it makes. I don't change the fluid much since I don't go through much water. The advanced auto brand and all the others are gl-5. This is for a d30/35.
