LUCAS has a use afterall ???

[FastSUV]

Okay so I have this Jeep I got with 65k a year & a half ago on the ticker and in good health at the time of purchase. I have since put on some miles (88k now) and the rear outer wheel bearing seals began to leak pretty good on both sides (typical for the Dana 35).

When I got the Jeep, I did full service on it including new diff fluid and at the time, I did 75w140 Royal Purple. This is the second rear end that began leaking on me after switching to synthetic gear oil BTW. Anyway, for now, I drained it and put in some MYSTIK 80w90 because it is dino gear oil and also claims on the back of the bottle to contain extra seal conditioners to slow/stop leaks. It appears to have slowed it almost completely on one side in a few 1000 miles of driving, but the otherside is slowed but still an issue & dripping onto the rotor backing plates. I know what all is involved to fix but I do not want to anytime soon since this is my beater daily driver and not my jewel.

I was thinking, maybe I have now identified a real time to try LUCAS dino oil stabilizer. I know it is not the best for the crankcase, but I ave used it a long time ago to quiet a worn diff and now I was wondering is 50% Lucas mixed with 50% Mystik might be my best shot to curb the leaks for awhile???

thoughts, experiences...yes, I am not a Lucas fan, but this "might" be the one time it is worth something?

Try it..... I would fix the seal. But that is just me.

It's fashionable to hate Lucas. I like LOS. I do not like their synthetic oils.

I like green eggs and ham.

Lucas Fashion!

It is unlikely that more sauce will fix it.

You would be better off using a sealer/conditioner such as found in Bar's Leak Rear main seal repair. This heavy polymer-enhanced sealer helped to stop several leaks on several high mileage engines and axles that we did not want to invest time to fix immediately.

I would fix the seals when the weather gets warmer. I don't like oil on my brakes.

I was not aware you could use that product in a gear box? At what ratio did you use in on a axle?

Yeah I know, but I wanted to try the seal conditioner route first while it is too cold to do the repair...I wish I had room for a press cause the dana 35 has the bearings and races pressed onto the axle shafts.

I used 8-12 oz of the Bar's stuff. It comes in a qt(32 oz).

Years ago, Bob, the original oil guy, demonstrated that the Lucas stuff in gear oil caused foaming. I'd stick with a seal conditioner until the time comes to renew the seals.
