Default Diff fluid check/fill on Firehawk

Hi!

Thanks to y2k_ta for pointing me where to get a replacement Fiehawk Owners Manual Supplement.

While I'm waiting for it to arrive does anyone have the specific instructions on checking and topping-up the fluid levels in the rear end? - do I remember there are specific procedures?

Thanks again,

Frank

Not that this is the correct way, but here's how I do it. Remove the fill plug and feel in the hole. If the fluid comes right up to the opening, then you're good to go. If you have to bend your finger down to feel the fluid, then you need to add fluid. If you have to add fluid, squirt it in the fill plug opening until it begins to come out of the hole. Screw the plug back in and enjoy! While you're down there, note if your pinion seal is leaking. If it's not, I'll be really surprised as most do.

I bought a bottle of diff. fluid from my local Napa that is already pre-mixed with the necessary additives to keep the rear quiet. I've never drained the original fluid, so what's still left in there has been in there for over 117,000 miles. So far so good.....

Soon I'll be switching my 2.73 gears/2-series carrier for 3.42 gears/3-series carrier. I'm also going to use a TA Performance Girdle. I'll upgrade to synthetic fluid at that time.
