@old-tank  from the 1956 Product Services Bulletins.  It may not apply to your 55 but it does make interesting reading.

Thanks John.  I doubt that seal is readily available.  That is the same type seal as used in the A-5 a/c compressor and by design those seals (vs the available lip seals) will slobber a little oil.  Anyhow the hub was not scored and if it was the fix nowadays would be to install a repair sleeve over the scored area. 

My guess is that there is a crack in either the torque converter or the front pump that spreads when hot.  Somewhere I saw a bulletin that described bolting the converter together on a bench with no "innards" and pressurizing with air while dunking in a tub of water.  Even then it might require hot water to find a crack.  If that transmission comes out again it will go a shelf to donate parts...never to be installed!  I've had all the fun I can stand.

Drove about 170 miles this weekend:  water pump is dry; radiator is dry; tranny still leaking but not as much (wishful thinking?) after the STP.  I will add another bottle after it leaks down.

Planned 300-400 mile trip (150 miles from home) this next weekend.  If stable it will go to OKC in June

Gotta get back to killin' bugs and killin' the planet :D.

I'd roll with it.  See what happens!

Thanks, but I should have a few hours to waste waiting on Haggerty roadside assistance.;)

Just throw a spare in the trunk, I’m sure by now you could  swap one out before Haggerty arrives. 

Sorry to see you having such difficulties, got to be frustrating

Found some that will work.  http://suspension.com

part number:  bulk-2007     $5.67 each, need four.MVIMG_20190227_161852779.thumb.jpg.b98869c59036e3eadc7d0bd2443cd107.jpg

 

 

They need some modification to fit:  the flange end is domed and is easily sanded, filed or ground down flat; they need to be cut to length...hose cutter worked for me.

They did not ship with lube, so buy some if you don't have on hand.

No sleeve. Other than the dome on the flange end and longer length they fit the 1 1/8 inch bore of the panhard bard and the the 5/8 inch pins.  They are installed, but no test drive yet.  I don't expect much difference from stock...just hope they last longer than the other available bushings.

"I don't expect much difference"  Wrong!  There is a huge difference.    Driving on crowned roads:  right lane or left lane (passing cars) it is as stable as any vehicle I own.  Same with high winds, up to 40 mph winds I have encountered (any direction)...I forgot I was driving a 55 Buick!  A combination of New + Polyurethane and the rear does not steer the car.  I am going to order some more for another 55.

Thanks for the check back Willie! I was seriously starting to think about a rear sway bar after my last jog over the mountains but now I have a much cheaper option to explore. As always, you are a great help to these forums and I appreciate you posting.
