maintaining rear end

[freshadenamufcka]

how often should the rear end fluids be changed? and what type of oil do use?

[Mr. Luos]

GM limited slip additive and 2 quarts of a good 75w-90.

Every 25K miles or so would be a decent interval.

[patriot1136]

Yeah go with what Mr. Luos said. Although I thought you could go a lot longer than 25k miles

I think GM recommended 10K miles.

For the power our cars have & the vast amount of power our ls1's can be modded to have, the rearend they "equipped" us with is a joke!

I think the recommended interval is 7000 miles if you can believe that.

[freshadenamufcka]

wait mr.lous was that 25,000 or 2500 sorry was kinda confused. i figured 25,000 would be way too long. also where can i buy the gm limited slip fluid and what rear gasket and 75/90 oil do you guys recommend?

[LETHALxLS1]

You can get the GM addative at the stealership or you can get pretty much its equivalent at Napa as well as the gasket, permatex sealant, 75/90 gear oil. I use Valvoline in mine.

[Mr. Luos]

For the stock rear end....and a mostly stock car.


Two quarts Mobil 1 75w-90 and GM additive from the stealership. Any gasket that will fit will do....with RTV (gasket maker) on it.

Use a good synthetic oil such as Royal Purple, Then you will not need the additive.

I do mine every spring when the car comes out of the storage unit. Mobil 1 75w90 and what ever LSD additive I can find at the parts store (usually kendal or atp.)

Damn-I think I may have put Royal Purple in mine-cant remember. I think I tacked 300 miles on my car this year.
