2.88 Diff: Use it, or sell it??? - PeachParts Mercedes-Benz Forum

TomJ · #1 11-21-2004, 01:33 PM

Pulled a 2.88 ratio diff out of a wrecked '85 300D a few weeks ago. Car had low miles (I think?) and diff was tanked and cover removed to examine/clean out. Everything is tight and in great shape. Was thinking of swapping in my 300D, but I like the accelleration I have with the current ratio diff.

I have some new side cover seals, pinion seal/nut that I thought I'd install in this diff and try it out in the car, but maybe I should just sell it as-is and save myself the work? Anyone in the Denver area have a 300D with a 2.88 I could test drive?

Opinions from those who've done this swap???

I've never driven in a car with a 2.88 so I can't help you there.... but I'll gladly take it off your hands if you decide to sell it!

Oooohhh!!! I'm second if you want to get rid of it! Cash in hand! RT

You don't really notice much difference in acceleration, but you do notice less RPM at highway and internet speeds. I installed a 2.88:1 differential in the 1982 300D (old one worn out) and also moved to 15" wheels and tires.

Better highway car because of it, and I don't really notice a difference around town.

Not enough of a difference to make it worth replacing a functional differential, but if you ever have to replace a worn one, that's the way to go.

OK. That's kind of what I figured. Might try 15" wheels and get as much as the 2.88. So...., if I do decide to sell it, what's a "fair" asking price for the diff to a forum member?

ROFLMAO!! What exactly, is internet speed?? Anyway, it seems to me that you'd want higher numerical ratios for better internet speed. :p

Errr, internet speeds? Got to have an 2.88 to improve those. BTW, I've got an 85 300CD and don't notice any difference in my internet speed.

I'm using the 2.88 in my 240D, automatic tranny. I love it, except for the 25% speedometer error.
