MusicCityBuick Posted October 6, 2022 Share Posted October 6, 2022 I have a ridiculously bad power steering fluid leak under my 1955 special. It looks like it’s close to where the transmission mounts to the engine. What could be leaking back there? Link to comment Share on other sites More sharing options...
rocketraider Posted October 6, 2022 Share Posted October 6, 2022 That sounds more like a transmission front seal. PS and Dynaflow both use transmission fluid. Are you losing power steering fluid? 1 1 Link to comment Share on other sites More sharing options...
MusicCityBuick Posted October 6, 2022 Author Share Posted October 6, 2022 Yes, the pump whines pretty loudly when I turn the wheel. It wasn’t doing that when I got it. The fluid appears reddish. I did read that red fluid is not correct for these pumps. Link to comment Share on other sites More sharing options...
60FlatTop Posted October 9, 2022 Share Posted October 9, 2022 The location you mention would be in the steering box area if it is on the left side. Get up in there and clean the steering box and lines. If you are lucky it might just be a hose. If it is a steering shaft seal consider a rebuild box instead of replacing just the seal. The shaft usually has enough wear to make a seal replacement ineffective. 1 Link to comment Share on other sites More sharing options...
avgwarhawk Posted October 9, 2022 Share Posted October 9, 2022 Possible pin size hole in PS hose shooting fluid at the area you see the fluid. 2 Link to comment Share on other sites More sharing options...

MusicCityBuick Posted October 10, 2022 Author Share Posted October 10, 2022 I opened the PS reservoir, and it’s nearly empty. Link to comment Share on other sites More sharing options...

Clear up the entire area round the pump, hoses and steering gear. Refill. Start the car and have someone turn the steering wheel lock to lock. The leak will present itself. If I were a guessing man I would say the leak is at the steering gear pitman arm shaft seal. Hopefully it is something easier to repair than the pitman arm shaft seal. 1 Link to comment Share on other sites More sharing options...

Seals gear oil, not power steering fluid unless the two fluids have mixed in that case you would have overflow out the top vent. Link to comment Share on other sites More sharing options...

Good to in know. The 54 is manual. The 60 power. Link to comment Share on other sites More sharing options...
KAD36 Posted October 11, 2022 Share Posted October 11, 2022 My guess is on the gasket at the flange at the end of the power cylinder. Has like 4 bolts going through it at end of cylinder bore, going off memory…. 1 1 Link to comment Share on other sites More sharing options...
drhach Posted October 14, 2022 Share Posted October 14, 2022 If the leak isn't immediately apparent, you can clean the outside of the system and wrap white towels around the hoses, fittings, etc. Anywhere parts don't move obviously. Leaking fluid has a tendency to migrate, especially in windy conditions. This can give a false impression about the origin of a leak. Putting a diaper on there will help to keep the leak localized. Go for a drive and then start checking the diapers. 1 Link to comment Share on other sites More sharing options...

drhach Posted October 15, 2022 Share Posted October 15, 2022 Yes, having them flop around defeats the purpose. Link to comment Share on other sites More sharing options...
