I checked my rear housing for cracks last night and I didn't notice anything and no leaks were found. The weld seams on mine are between the two vertical "ears" that the lower control arm bolts to and they don't appear to have ever been ground smooth.
While I had it up in the air, I swapped out the transmission x-member that had been custom made by the individual I purchased the original box-o-kit car-parts from, I noticed that I had this after investigating Roscoe's web site and in one of your pictures I saw a "C" channel style flat x-member. For some reason this guy(or someone) decided it was necessary to have a x-member with a 2.5" drop in it. Well, after swapping this with the correct one that I still had in my box-o-parts, it raised the tailshaft of my transmission quite a bit which made my driveshaft almost straight back into the pinion. Now I may not have to flatten the tires on my friends trailer to get it on and off due to catching the transmission pan on the back of his trailer. I also removed my driveshaft from Denny's (like yours Roscoe) and inspected the rear u-joint bearings. I removed the bearing caps to inspect and noticed what I perceived to be the smell of burning
oil/grease. I re-installed the caps as there was still plenty of grease in the caps and spun them by hand several times to redistribute the grease through the bearings.
I also went through all the drivetrain bolts while I was under there and insured everything was tight.
After all that, down it went and to the highway ----- VIOLA ----- almost all of the vibrations are gone. I still have a slight front end vibration which I still have not corrected the runout issue on the front rotors and will look at the tire truing idea and see if I can find someone to do this.
Thank you all for listening and giving your inputs.
John.
