Like the title says i just bought a 2000 s2000 for 5k. Bretty good deal considering it has a willwood 6 piston big brake kit koyo radiator BC type RS 32 way adjustable coilovers glass window soft top (does have 3 patches but was assured that it dosent leak) HKS Dual exhaust dual piller with Delphi gauges AEM intake DC sport header a cabon fiber rear lip and cooling plate. The body and interior are not the greatest but has 75k on the engine. Reason i got it so cheap is the differintial grinds real bad when i try to move it. Does this mean the diff is shot. If so is it possible to rebuild it. Or maby someone here has a good one for sale. Ill post pics when i can.
Thanks for the help in advance

i've seen differentials sell on ebay. i think they range around $500

btw congrats on your purchase. sounds like it could work out to be a good deal.

 

Hope fully. Any chance someone knows of a diy rebuild thread for the diff. Was reading about changing the diff gears. Where is a good place to get 4.4s??? Im a competent mechanic and would rebuild the diff if possible.
Thanks again
Eddie

 

Anyone know of a good diy diff rebuild writeup

 

For salvage diff try craigslist. This guy is 2-3 hrs from you: http://cincinnati.craigslist.org/pts/1938754980.html

Or try http://www.car-part.com/index.htm

 

i'd suggest just going with 4.77

 

What all is needed to do a fd swap and where is the cheapest place to get it

 

Any link to a diff rebuild would be helpful

 

Well heres an update. I finnaly got a chance to jack up the car and found the rear drivers side cv boot is twisted. Its the side attached to the pumpkin. Would that be a cause for a bad grinding noise when i try to move the car. Reason i ask is i disconected the axle off the diff and tried to duplicate the noise and now the car dosent move but it also dosent grind any more.
Thanks for your help in advance

people on s2ki.com are sellin stock AP1 and AP2 diffs from 300 to 500 dollars right now, also try and find a stock header as well jkjkjkjkjkjk great buy!!!!

 

That might have been your problem, pick up a new axle and see if it fixes the problem.

 

thats most likley the axle i had the same problem broke my driverside one but i ruined my diff as well had teeth missin on the ring and the pinion was kinda torn up but gl and conrats on the perchase

 

So right now you just removed one shaft, tried to drive the car and it does not move? The reason for this is because the diff will apply force to the output with the least resistance. SAFELY jack up the rear of the car entirely (wheels off ground), have someone put it in first gear and release the clutch (while running). Now look under the rear end and see if the drive shaft is spinning, and then see if the output flange on the diff (that connects to the axle) is spinning. If both are and you do not hear a sound, all you need is an axle. (There could be other parts damaged in the hub assembly.)

 

Dude said he's a competent mechanic, surely he knows that plus the car didn't move before he removed the axle either.
Now that an axle is off an you can get an output shaft to turn without grinding, pinion and FD gear are probably okay but something in the inner diff assembly is blown. Getting a used differ is still probably going to be easier and cheaper than a rebuild.
