Re: [Chrysler300] Driving Mr. Barber





You are right about that , Sheldon-- although dropping at the rear is no party either at 3000 rpm . I think driveshaft loops should be safety things---things  that really matter , like dual masters .
After several personal incidents with burst brake lines ( still a problem in 2026) ( anyone have a Dakota?) I once ,in my idealistic youth, wrote to NHTSA or whatever it is about requiring stainless lines . Maybe 20 years ago . Old cars end up with low income people --they end up hurt . I ended up crashed twice in my life with old cars due to burst lines . Could have been much worse.  The day you really mash the brakes it bursts , pedal goes to floor . .  I received a nicely written report from a clueless young woman ( with a degree!) saying " it cost too much " . I priced out 20 feet of each .", retail. ,0ne was 9$ and one was $ 16 ...I .sent it to her . Nothing back .  I now realize gov't has no paddle at all, in all things . Only what lobbyists pay them off to do gets done . All big hats,  no cattle . But we got the big rubber pads on the bumpers to save the insurance companies money . "It's the law" 
Imagine the lives saved with stainless lines? For 7$ ?

The big advantage to the b&t joint is that it would be almost impossible for the drive shaft  to drop in the event of a failure.
I believe this is why they continued to use them in the front even after they changed in the rear.
It would prevent an unfortunate 'pole-vaulting' event.

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.

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.

I have done this .. Way to go .the old one is a very poor design . Good only for flat six . That is a great price . Maybe make some deal w club --send our shafts there . Even with 100$ ship if they are good and do it well it is a great deal . Too many duffers will ruin shaft . You need to be skilled to do perfectly , have right equipment . Nice find Rob .

The flanged Fitting for a modern joint is used on Winnebago motor homes , not an uncommon part .

Hello 300’ly to all!

I just replaced the front ball and trunion u-joint assembly on my C with the upgrade of the slip assembly more modern front u-joint and I must say that I could not be more pleased. The car runs as smooth as silk and is quieter. It almost feels like the vehicle is at peace with itself! I had tremors develop between 30 and 40 mph upon easy acceleration and again when accelerating above 60mph. The front U-joint had 1/16th inch play. The grease retention boot was replaced a month ago when discovered that it left the party who knows how long ago. The new u-joint was installed to the front of the driveshaft which was balanced with the rear u-joint in place and then installed. Precision Drive Shaft in Oklahoma City did all the work and obtained all the parts . 3 day turn around time. $298.00. Many thanks to Club members Mike Burke, George McKovich, Larry Jett, Murray Park and Jeff Carter for discussing the upgrade and helping me decide to go this route! Rob Kern
