I'll give my two cents. I had similar issues recently. I fixed it yesterday. I tried a few things. I messed with pinion angle numerous times. My tailshaft bushing looked perfect and had min play in it. I put another tailshaft housing in with a new bushing installed. I also spent extra time to make sure the ujoints were fully seated in the rear. Very easy to mess that up the way these splicer joints fit so tight. I tapped them into the seat with a rubber mallet.

My vibration is gone! For the small price a bushing costs, it would be worth a try.

Edit, I reread the thread. Seems you have already tried this.

I HAVE THAT PROBLEM! I thought I had to be crazy since I bought it from summit and it was for a T56 but I guess not. What all did you to do rectify the problem?

Mine was a low mile transmission, so I knew the problem wasnt the bushing. So I ordered a new yoke from Mark Williams. Strange wasn't really much help with the yoke, they test fit one on one of their cars, said it fit right and they were all machined the same. They took it back though, so that was good. I read a couple of other people having problems with the strange C/M yoke. The Mark Williams yoke fit much tighter on the splines, the barrel diameter was a few thousandths bigger and it made the problem disappear. Now I switched to a 32 spline yoke, so if you need a 27, let me know. I am selling mine.

I need it! mine actually has a slight leak! How much are you asking and does it have a 1350 joint?

So is Strange replacing these with properly tolerenced parts?

I have to get to work now, but will mic it tonight and see if the OD is different.

I just got my transmission in Sunday and bought the PST DS with the Strange yoke last fall from a site sponsor. After reading this thread I went out and tried the fit and guess what, it has play. My 7 year old 350 pass Spicer is nice and tight with no play. The Strange is sloppy in fit, WTF?

Any way I bought it from a sponsor and just sent him an email to see what the options are.

Any one else had PST resolve this?

I think their opinion was that my car was some kind of fluke. I think that the way that the splines are cut/rolled, however they do it, is the problem. The O.D. was pretty close, but there is alot of difference in the splines. The Mark Williams yoke fit my car alot better.

I have measured both the Spicer and the Strange Yokes. The Strange is 1.4995 OD and the Spicer was 1.5021 OD. When the picer is on there feels like there is zero play, the Strange moves alot. I plan to try them on and use a dial indicator to show movement at the u jonts center to see the difference out there.

I think you might have something on the slpines fit though. I need to check for rotational play too.

Who sells the Mark Williams unit?

Mark Williams and Denny's driveshaft. I have a slightly used one if anyone is interested.

This was my problem as well. I swapped it out with a Spicer yoke and the vibration is gone. The U1667 I have is stamped 09/07 so it seems to be an older unit.
