I am reassembling the suspension on my '37 120 Sedan and three out of the four shock absorbers are not absorbing. I have three options, 1) refill them and see if that cures the ills, 2) rebuild them, refill them and see if that cures the ills or 3) buy new ones to replace these three. I would like to try to just refill them first and have the oil information from the shop manual, but I would like to see if any of you have more information concerning the type of oil and also where I might obtain it. Also, the manual specifies a specific gun to use to refill these and any information concerning this mechanism would also be helpful. I know those part numbers for the oil and the gun from the shop manual are no longer available. If option 1 is not feasible, the I would also think option 2 would be out of the question. Thanks to all in the Forum and also for the help you have given me thus far.

Thanks, Convert. I'm not quite to the point of actually removing the drums yet, but just wanted the information on how they went back on. I'm still not understanding as to why it takes a heavy duty puller to remove them, but they then just slip back on without requiring the same amount of force in the opposite direction to reinstall them. Does it have something to do with the tapered shaft?

I have been reading the information and doing research on how to remove the rear brake drums so I can redo the brakes on my '37 Touring Sedan. From what I've read, the fronts will come off fairly easily, so that should be no problem. However, I have not located anything in my research on the best way to reinstall said back brake drums. I would not think you would beat on them with a hammer until they popped back into place. What would any of you out there suggest would be the best way of getting these back on so I don't have a surprise as I am going down the highway?
