DIY Request

ithatel · 08-06-2008, 11:52 AM

I used the DIY by MR. 5 to change my manual tranny fluid yesterday (thanks Mr. 5 eyerything was as you posted) and then went back to change the diff fluid.
This will have to wait until I get a hex large enough for the drain plug, but where do you fill the diff ?? I see the drain plug, but feeling around the top of the diff, I could not find a fill plug. Also, what size hex is needed for the fill plug.
Or do you syphon out the fluid and refill using this same fill plug ??
Thanks, in advance
Doug

There isn't a drain plug, only a fill plug. You need to use an extractor to remove the old fluid. Such is life with "Lifetime Fill" lubricants...

When installing a clutch-type LSD the diff cover is typically replaced with one that has a drain plug.
