1j driveshaft difference

[staticpage]

I conform what bkma71 is saying
I slid my w58 DS in last night it goes all the way in but then the carrier bearing wont bolt up then it's short in the back by 2 cm. I figured it might make it weak as the ds not being loaded buy the full length of the output shaft.

so when i put my r154 in after rebuilding it what DS should i use in a 89?

How did you slide a W58 shaft in? They have different splines on the front yoke?

It's a w58 trans and a w58 drive shaft thats how. it's just to short.
i am afraid that when i get my r154 set up together it will be the same, sort and If i make any power like i want to I'll strip the splines from the shaft or trans.

I had no issues with my Ma71 DS when i did my 1J swap and did not notice any issues. What i think we really need is a canadian with a full JZA70 to remove there DS and measure it to see if we can confirm the difference. Maybe Garage Fuji can chime in here even.

Jeff why is it that only the second set of numbers are different for those parts could it just be country related more then part related?

 

[Jeff Lange]

Not country related. All those numbers are from the Japanese A70 catalog.

The Japanese MA70 used the same parts as our MA70.

Next time I'm under a real JZA70, I'll measure one. I should be able to get under a TT-R in the next week or so... though may not UNDER it... we'll see.

Not sure why it really matters though, since clearly the MA70 shaft works; I guess having more spline is always nice though.

this thread is old, yes.. but I thought I would post some pics of the GENUINE JZA70 shaft taken directly from a TT-R. This particular shaft also includes the newer style carrier bearing (believe the same ones used on certain mkiv models)

this pics are of another shaft, but I have an identical one sitting right next to me as well:

I'm running the same 1-piece AL DS that was on my 7M, now on my 1JZ. No leaks or any issues what so ever, taken RPMs up to ~8500 once or twice too.
