Need axle lube advice for 03 TB
Want to change the fluid on both axles. Don't know what type or amount to used since i bought the vehicle used w/ no manual. Can someone recommend a brand and amount to use. Would like to go synthetic. Thanks!

Welcome to AF. 75-90 Mobil 1 synthetic is your best choice here, should do the tranfer case also. GM has a special fluid for that , Autotrak to be exact.

Re: Need axle lube advice for 03 TB
it don't take fluid it takes grease. you probabley going to have to buy new boots if your removing them just to change grease. the easy way is just buy both half shafts. but if you want grease you can buy at any parts store it's usually green.

Re: Need axle lube advice for 03 TB
Mobil 1 75W-90 should work just fine for front and rear differentials. I don't recall the type of limited slip differentials (G-80 option code) used in these vehicles, but if your vehicle has limited slip, look in your Owners Manual to see if a limited slip additive is required. Routine service of the front drive axle joint grease is not required. Your Owners Manual will also give you the required amount of lube.

Re: Need axle lube advice for 03 TB
The Eaton locking diff. does not reqiuire any additive. BTW I don't think he meant the cv joints.

Re: Need axle lube advice for 03 TB
Stay away from synthetic gear lube,too hard on gears.I know of 3 rear ends going due to synthetic gear lube.I know a guy that has replaced ring and pinions due to synthetic gear lube,down to pencil tip

Re: Need axle lube advice for 03 TB
Synthetic causing this, I don't think so, used it in my pictured race car, 650 hp, never did any damage to the ring and pinion that could be attributed to the syn fluid, plus I have 120k on my TB no issues. Service customers trucks in my shop also with no issues.

Re: Need axle lube advice for 03 TB
I agree, the guy is rebuilding rear ends for other reasons. Synthetic lube is an upgrade over regular petroleum lube. General Motors has been using synthetic differential lube for a long time now on millions of differentials with no lubrication issues. Just be sure you are using the correct weight and lube rating (GL-4 Vs. GL-5).

Re: Need axle lube advice for 03 TB
Thanks for all the info guys. I bought M1 75W- 90. I also bought some "Equa Torque" limited slip additive (made by CRC). It says it's for GM #1052358 diff's. Since i don't have an owners manual i have no idea as to what type of diff's. it has. Is there an axle tag somewhere that i can decode? I guess i could just call my dealer. It's a 20003 TB- "LT" with AWD. I'm assuming it takes 2 qts. per axle.

Re: Need axle lube advice for 03 TB
This is true,this guy,my father's friend Rich worked on one customer's rear end replacing the ring and pinion due to synthetic gear lube.The rear end was fine before the switch to synthetic gear lube and was really noisey after switching to synthetic gear lube with the teeth down to a pencil tip.Synthetic gear lube is not recomended for detroit lockers either and my father's friend Rich was told this where he got a 9 inch ford with a detroit locker for a 1983 Monte Carlo he has.
