Re: Yup, they were right.



Did you break in the new clutches by making several tight turns in each direction, or did you go straight to burnouts?

More woes.  The new yoke was a very tight fit and I had a hard time getting it installed. Got in a hurry and used a socket and hammer to pound it on.  I should  know better than that , but it was at night and no other way to put it on then.  SOOO, now I have a gear or bearing whine/growl  comeing from the rear at 1800-2200 RPM in high gear under slight acceleration.   ....Does a 742 differential have a crush sleeve on the pinion ? 
  Also.. This differential was completly re-built with  new ring and pinion , and the clutch type sure grip overhauled.  Bought on e bay from a vendor. The sure grip worked well  with old hard street tires, but after putting on the sticky Nittos, it just lays a little bit of rubber on the right tire track. I am using regular diff gear oil with the Mopar  additive for sure grip.  I would guess the clutch disc in the S.G. is slipping to much?  Any idea's or solutions? ......................MO

It is a broken rear yoke, and of course ruined a U joint.  Put a ding in the driveshaft, but I think it will be OK. The driveshaft was set up for  7290 U joints, but the diff .yoke is for a 7260 using a combo U joint.  I will get a 7290 yoke that uses  the U bolts instead of the cap straps. Crunch time as the local car show is Saturday. ....................................MO

New Nitto drag radials  are mounted . First try out of a medium launch  on new heavy duty springs resulted in what I think was the stock snubber whacking the floor and a big  fuel bog. 4 speed tranny and sure- lock  I just finished  clamping  the leaf springs- two on the front segment and one on the back segment ( per side).  It sure stiiffened up those springs. 
 They were right-- get some traction tires and the next weak link will show up.  Still have the fuel bog.  The driveshaft let loose at I think a U joint. Stuck out on a highway, getting towards dark , and very little shoulder.  Got the car pulled to a side road and called a tow truck. . He was able to park it right in my garage. I was so aggravated , I didn't want to even look...afraid to find a broken yoke and a bent driveshaft.( new)..  I will find out the bad news tomorrow..............................MO
