2000 PY ITR - roughly 28k miles

A few friends took a spirited drive today while we the rest of us were doing the F1 road course drive-through. I come home and find out that his tranny took a major ****. The car apparently drove fine the entire time and all the way back home.

But, as soon as Justin goes to put the car in reverse to back out of the driveway, the car makes some funky clanking noises. The car would free rev while in gear and the clutch pedal out.

So, they go to put the car back into a spot and as they're pushing the car, it makes some more clunking noises. It did this the entire time (pushing it forwards or backwards) while trying to get it into the garage.

At this point, I'm thinking that either the clutch, differential, or axle/diff splines are shot.

When rotating the axle by hand, there seems to be significant amounts of play before it starts engaging/resisting. It's worse on the passenger-side than on the driver-side axle. Also, I can turn the axles by hand even tho the car is in gear.

I've popped the passenger-side axle out and the splines on both sides of the axles and tranny are good.

Gear sets are deemed good for now b/c I can get the car into any gear with the clutch pedal in, as well as any gear while the car is off.

Sounds like the diff is shot at this point. Tranny comes down tomorrow, but I'd still like to hear other POV's.

 

it may be the clutch

 

If it is the clutch, he would have had to have blown all the friction material on the clutch off. I've only seen that happen one other time, on a FC. It only left the skeleton of the clutch. All the friction material just crumbled out when the tranny was removed.

Anyways, we were up at IMS for the F1 drive thing b/c my roommate just got an Evo 8 (same color as cheeze's), and some news anchor guy that was there the same day Kevin took delivery of the car ended up chatting with me about the car (then about the F1 races in Sept) and somewhere along the line, he ended up giving him a complimentary ticket for the road course drive.

Update:

We put the axles in the tranny and rotated one of the axles, the other axle will briefly grab and then slip.

Is this normal, or is the diff definitely dead?

 

ive had a similar problem, its probably your spyder gears , 1 of the 4 gears are grinded down.ive went through 3 trannies the past year an a half it sucks.im know useing 1-4 type r and 5 and reverse with type r final drive its great till 5 then rpms drop to 3500.

ITR Differential doesnt have spider gears....

 

I take it back when I said that the axles were good.

The passenger-side axle outer CV joint is dead. It clanks when you shake it and you can definitely feel loose bits and pieces beneath the boot. the axles are DSS stage 3's.

But, I don't think it's for naught that we dropped the tranny and tranny casing. I still think the diff is dead.

We've tried and tested it several ways now.

Plugging a couple of axles into a spare GS-R tranny....opposing axle turns, in opposite direction. Good solid feel. Open diff = same expected results?

With someone holding the final drive ring gear in one place, we've tried turning one of the axles and the other axle still doesn't move like I think it's supposed to. It just catches slightly and then slips. However, the slower you turn it, the more proficient it is at also turning the other axle in the opposite direction. Turn it faster and it slips.

If indeed, both the axle and diff are dead, then the axle probably ate the diff.

We finally found the problem.

The DSS stage 3 axles (older line of axles) he has must have completely demolished the CV joint and maybe the torsion bar too.

DSS fixed the axle and it's on its way back to us.

We had thought that the LSD died along with it, but after plugging two known good axles in, the LSD functions as expected.

And to think that we disassembled everything down to the diff for nothing. A new passenger-side axle would have fixed it on the spot. The inner torsion bar had me tricked. If it was an OEM axle, I would have known it was the axle only right away. I'll never make that mistake again.

I did get to take apart and re-assemble a tranny inside-out for the first time. Hardest parts are putting the casing back on and setting the retainer clip back into its groove on the countershaft bearing.
