when installing spring shackles, because of the extremly tight fit, should you use any lubricant on the outside or press them in dry. these are going in a stock 35 coupe. Thanks Gary.
 
Gary, are you planning to use some type of press fixture/tool maybe like the one K.R.W. made, or something similar? A press tool would make the job much easier. I would suggest using some type of lube, maybe a dry lube.The formed sheet metal cans that go over the shackle studs are a very tight press fit going into the spring eyes and the ends of the wishbone/radius rods. To reduce this press fit, some recommend sanding/machining a little material off the OD of the sheet metal can. Doing a real good cleaning of the spring eyes and other shackle mounting diameters is a must. One thing you don't want to do is try to drive those spring shackle studs into their mounting diameters when they are a heavy/tight press fit. The sheet metal cans will distort/mushroom and be ruined. Good luck, J.M.
 
Thanks, I don't have a press, I tried a deep well socket over the shackle and started pressing in in with a c clamp I just started on one and that was in a spring, the ones i dread are the ones in the rear radius rods.
 
There is a .003" to .004" press fit designed into these pins.
I use the KR Wilson tool and the pins go in smoothly. Do NOT attempt to pound them in.
Also, sanding them down defeats the purpose of replacing them.
