I submit that the old U-joint design was great for strength, but not so good in that the probability of proper long-term maintenance, lubrication and protection of the joint was low—leading to failure. The old design required that the boot hold up forever or be regularly inspected and promptly replaced (yes, difficult) if ripped, split, torn or otherwise leaking grease out and dirt and water in. The Spicer joints used to have a grease fitting on them that would facilitate periodically displacing old and aging grease with fresh. But, we lubed the chassis and U-joints every thousand miles or so. Failure to lube the joint periodically led to really nasty failures. I had a hip joint replaced five years ago and my surgeon told me that joint is surrounded by a muscular and flexible capsule that holds synovial lubricating fluid. This capsule is opened for the surgery and sewed back up afterward so the Ti and HDPE joint will also be lubricated. The original patent is pending but it comes with a lifetime guarantee. Rich Barber Rainy Brentwood, CA From: Chrysler300@xxxxxxxxxxxxxxx [mailto:Chrysler300@xxxxxxxxxxxxxxx] On Behalf Of 'Jack Boyle' jackcboyle@xxxxxxxxx [Chrysler300] I have had the original B&T joint in my C-300 for 115,000 miles. I rebuilt it the 70’s at 50,000 miles and replaced a few pins and the buttons last year before we drove it to Chicago and on to Oklahoma on route 66. I think, taken care of they handle much more than an L-head 6. __._,_.___ Posted by: "Rich Barber" <c300@xxxxxxx> To send a message to this group, send an email to: Chrysler300@xxxxxxxxxxxxxxx To unsubscribe from this group, send an email to bob@xxxxxxxxxxxxx or go to https://groups.yahoo.com/neo/groups/all/manage/edit For list server instructions, go to http://www.chrysler300club.com/yahoolist/inst.htm For archives go to http://www.forwardlook.net/300-archive/search.htm#querylang __,_._,___ |
