Title: Nightmares with POLARACO
Post by: Steve on June 05, 2010, 12:26:58 PM
For the last three years I have had a vibration in the drive line.  At 60 and above I would have a grumbling noise in the drive shaft when the drive train and car speed were synced.
 
I had concluded it was a rear tail shaft bushing.  Changing it wasn't going to be easy, but I found a friend who had the exact tools needed to pull the bushing.
 
AFTER 3 YEARS, I finally got the car on a lift.  Yipee!  30 minutes later the task was done.
 
As I cruised under the car, it's the first time I was able to walk it since I built the car, I saw some rust around the pinion nut.  What the. .  .  Started to check it out and found the yoke loose.  Too LATE. . .   The damage to the yoke is done.  Apparently the pinion nut had loosened up some time over the two years.  I didn't build this rear.
 
Dis what we could with it.  I have a 323 here I pulled from the VOAB. . .  So I am going to throw that in.  The current rear is a 355.  I'll drop a hondred RPM.  I was going to go with a 294, but I don't have it yet.
 
Pete drove the car, he said it pulls like his 383 HP in his Fury.  That was good to hear.

So is there damage to the splines on the pinion shaft itself??

Both Lea.  You don't find ring and pinions for a 741 case too often anymore.  I was lucky and found them new for this build.  A yoke will probably get rid of the noise. . .   But I need a good one off a 741 case.

Well just like Leaburn...you procrastinate for so long about certain things and then when you actually get around to doing them it doesn't take too long.

Glad you found the problems.

Yeah   Me too.  I was trying to build a classic luxury car.  Sort of a silk purse out of a sows ear
