Guest imported_NikeAjax Posted March 18, 2005 Share Posted March 18, 2005 I have a ?56 Century and what I suspect is happening is this: the inner torque ball is bad and is allowing the ATF the run through the torque tube and fill the differential with ATF. The overflow on the axel is dripping, with a thinner oil than the hypoid oil that should come out of it. Also, when I removed the plug, I heard a whooshing sound; under a slight pressure maybe? I was wondering many times where the ATF was going?!?!?! Has this happened to anyone else?Jaybird Link to comment Share on other sites More sharing options...
Centurion Posted March 18, 2005 Share Posted March 18, 2005 While it has not happened to me, I have read several times that this is something to watch for when the torque ball seal is bad. I would work to remedy the problem as quickly as possible, since the ATF is said to ruin the differential gears. Make certain that the differential is completely drained and re-filled with the correct gear oil. Link to comment Share on other sites More sharing options...
Judd Posted March 18, 2005 Share Posted March 18, 2005 Nike Ther is a seal at the front of the torque tube also. Link to comment Share on other sites More sharing options...
Guest imported_MrEarl Posted March 18, 2005 Share Posted March 18, 2005 You can drill a small hole in the low end of the torque tube at the rear end that will allow an inspection to see if there is indeed ATF in the tube. Screw a small screw in it that can be removed and replaced ever so often for inspection. Link to comment Share on other sites More sharing options...
old-tank Posted March 18, 2005 Share Posted March 18, 2005 Sounds like the seal at the front of the torque and the pinon seal is leaking. I also recommend drilling a hole in the torque tube to check/drain fluid. If your pinion seal is good the torque tube will fill with trans fluid and it will get inside the driveshaft and give bad vibration problems.The part about trans fluid ruining rear ends is probably sometimes true, but personal experience is different.My origianl 55 Special routinely filled the rear with trans fluid to the point of leaking out of the axel seals and contaminating the brakes...usually washed the brakes with gasoline and removed the fill plug to drain it back to a normal level. If I had time and money I would pull the bottom cover bolt, drain the whole thing and refill with cheap hypoid 90 that did not have the recommended wear inhibitors. Anyhow that rear went about 250,000 miles (car croaked at 374,000 mi) with various dilutions of trans fluid in the rear. I pulled ther rear end a few years ago and rebuilt it...other than a few pits in one of the pinion bearing and an axel bearing there was no abnormal wear. I just cleaned it, replaced the bearings and pinion seal...it is now happy in my CVT.Willie Link to comment Share on other sites More sharing options...
Guest imported_NikeAjax Posted March 18, 2005 Share Posted March 18, 2005 Does anyone know where I can find the inner and outer torque ball kit? I ordered one but I only got the outer one and was stuck so I had to put the thing back together with a faked inner seal.Thanks,Jaybird Link to comment Share on other sites More sharing options...

Is this port not on the '56? Link to comment Share on other sites More sharing options...

Judd Posted March 18, 2005 Share Posted March 18, 2005 Jaybird The only way I've found the correct torque ball seal for a 56 is NOS on e-bay the last one went for over $100. I think Steele rubber (1-800-544-88665)will rebuild your old seal. Link to comment Share on other sites More sharing options...
JohnD1956 Posted March 19, 2005 Share Posted March 19, 2005 The 56 does not have this port Dave. What is the orientation of this port anyway, 6:00 on the tube? JD Link to comment Share on other sites More sharing options...
Dave@Moon Posted March 19, 2005 Share Posted March 19, 2005 As I recall the plug is at around 5:00, not quite pointing straight down but low enough that I could stick my finger in there an check for fluid. Link to comment Share on other sites More sharing options...
