Car Forum / Driving, Maintenance, Tuning / 4x4 Cars / February 2005differential fluid
I have an 03 Tundra with 4WD TRD off road and Limited Slip Differential which requires special differential fluid. If plain differential fluid was added to my truck what are the dangers, if any? SteveT No dangers but the limited slip will slip... special diff fluids provide some friction additives which will help the slip not slip as much. Use these and dont worry .. Slips wear out over time ... then you canuse whatever you want. Matt You will burn out the diff so the limited slip will no longer work. Although if you can find freaking gear oil without the damn limited slip additive, let us know will ya? I looked in all the auto stores around here and only could find a 'semi-synthetic' that didn't have the additive. My Tranny uses 'plain' gear oil and short of getting robbed at the $tealership it is hard to find.

I know of no gear oil that has (by default) the additive (like ATF, the additive is 'supposed' to be different for different makes)! I use Lucas oils, and am happy with them, no additive that I know of... But, I will look again to see what is out there. Maybe things have changed, and I didn't notice. You are usually knowledgeable, so it is worth looking into. >Although if you can find freaking gear oil without the damn limited slip >additive, let us know will ya?

I know, I had everything drained and went to the stores and couldn't get a gear oil without the 'friction modifier' already added in and I was on my way for a 10 day bush run the next morning.... Pissed me right off, but the semi synthetic seems to work ok in the T5 tranny and the rear and front ends didn't mind the stuff with the additive I hope.... Mike > Uh, Mike, that didn't make sense.

Any diff, with or w/o LSD still has a ring and pinion gear, not to mention bearings. The friction modifier only works on the clutch pack, nothing else is affected. -PapaRick ----------------- > I know, I had everything drained and went to the stores and couldn't get > a gear oil without the 'friction modifier' already added in and I was on [quoted text clipped - 20 lines] >>>additive. My Tranny uses 'plain' gear oil and short of getting robbed >>>at the $tealership it is hard to find. My Tranny is the Borg Warner World Class T5 with something fancy called synchromesh in it..... The only gear oils I could find were GL4 + GL5 'compatible' with the additive. It will NOT shift gears using that oil without jamming and grinding. My main point was I couldn't find any oil without the additive, the OP was having the opposite issues I believe. Mike > The LSD additive will NOT hurt hypoid gears, how could it?

[quoted text clipped - 53 lines] > hth, > Bret Thanks, I ended up with a semi synthetic GL4 that works nice. Should do me for a few years or until the next leak. Mike My '76 CJ-7 had syncro in 1st gear (Tremac T-15), is that different than B-W T5 w/ syncro? Is this in your Jeep? (Btw, if you think syncromesh gears is something fancy, you're a heck of a lot older than I thought.) -PapaRick ------------------ > My Tranny is the Borg Warner World Class T5 with something fancy called > synchromesh in it..... [quoted text clipped - 40 lines] >>>>>additive. My Tranny uses 'plain' gear oil and short of getting robbed >>>>>at the $tealership it is hard to find. Yup, the Jeep. The BW has all the gears syncro and they don't like the GL 5 oils or the friction modifier. The book says you 'can' top it up with a GL5 if needed, but to only use a GL4 for a fill. I remember when electronic ignition was new fangled too.... ;-) Mike 86/00 CJ7 Laredo, 33x9.5 BFG Muds, 'glass nose to tail in '00 88 Cherokee 235 BFG AT's > My '76 CJ-7 had syncro in 1st gear (Tremac T-15), is that different than > B-W T5 w/ syncro?
