Technical Ok I’ve made a decision, Buick Dynaflow.

Easy to see that having help at least at certain points is a good idea. In any case, as Pist-n-Broke said, you need good equipment.

oldbuickparts.com, (908-369-3666) purchased parts for our 51 Roadmaster, found Buick and dynaflow manuals on Ebay. I replaced torque ball seal with trans in car, have to remove coil springs and a few other things to move driveline back. I did this on my 4 post lift, body lift pretty high even using coil spring compressor to get coils out. I'm an old timer and thought the job was not too bad, but a real PIA for me to do. I originally went to Buick forums and there's only a few places to call that rebuild dynaflows and prices quoted were $4500/$6000, out of the question, so I did it myself, worked out fine as it went to a pint/3000 miles leaking, pretty good I was told by old timers as they leaked when new. My wife loved that Buick, enjoyed cruising/showing/etc. had a lot of fun with it. We have moved on and my Merc is the last old car left as time/age have taken away garage fun, now just too much work for me. Good Luck with your Buick, looks slick/Kool.

 

Thanks guys
Kinda what I figured not a complicated job just big and heavy.
The leak started as a small drip from the torque converter area then ended you pissing out the torque ball by the end of the summer
Tried luckas stop leak-nope- but for $10 bucks why not! Lol

Most likely will yank it all out as I want to detail it all and clean it up.

Any seals or bushings to replace in the torque tube/ diff while it’s out?

 

The rear axle bearings need greasing every 25,000 miles, and there are two seals per side, one on the inside and one on the outside of the bearing. There should also be a lip seal at the front of the torque tube (where it bolts to the transmission); you should replace that and check the surface of the driveshaft as well.

I'm not sure if '55s had a separate axle vent, but my '53 did not. When I replaced the original seals with lip seals, I had to make a vent; I eventually used a threaded hose nipple and used it to replace one of the axle cover plate bolts. Then, I attached a hose and a fuel filter to keep trash out of the axle. I'm sure there are other ways to do it.

 

I'm only 63 and in good shape. My son recently chased me off the ladder when I was cleaning out the 1st story gutters of leaves and pine needles. He did note that I take one step for every rung, he takes 2...

 

The best jack to use on the dynaflows is a flat motorcycle jack. I used it when I rebuilt my dynaflow and and my 56 cad jetaway worked perfect.
