jgreg53 Posted May 3, 2023 Report Share Posted May 3, 2023 I'm trying to change body mounts on my 48. I loosened the driver side mounts and took the fasteners off the passenger side. I'm having a heck of a time getting body and frame to separate enough to get a couple of the old mounts completely off. Any suggestions?

The steering column is the first one that comes to mind. The front clip needs to be free'd up also. Quote Link to comment Share on other sites More sharing options...
Plymouthy Adams Posted May 3, 2023 Report Share Posted May 3, 2023 at the firewall lower corners, remove these capture nuts....on the passenger side at the top of the axle tip is a mounted isolation pad also...and then oftne the two at the trunk corners get over looked....hard to lift the middle when the ends are still secured.

jgreg53 Posted May 3, 2023 Report Share Posted May 3, 2023 (edited) Would someone have pics of these capture nuts? My shop manual shows 5 on each side. Edited May 3, 2023 by jgreg53 Quote Link to comment Share on other sites More sharing options...
Sniper Posted May 3, 2023 Report Share Posted May 3, 2023 the frame section of the parts manual can be helpful here. Quote Link to comment Share on other sites More sharing options...
jgreg53 Posted May 5, 2023 Report Share Posted May 5, 2023 (edited) The two mounts right below the front doors are stuck, big time. The bolts going through the floor in into the frame are seized in their holes. Could this keep the frame from separating? Also, I took the steering box loose.

jgreg53 Posted May 6, 2023 Report Share Posted May 6, 2023 Well, I'm officially throwing in the towel. Bolts are seized in the frame. It shows no signs of separation. The job is over my head. Quote Link to comment Share on other sites More sharing options...
jgreg53 Posted May 10, 2023 Report Share Posted May 10, 2023 The connections at the firewall corners have no rubber bushings. Is this normal? I'm going to put some in anyway. Quote Link to comment Share on other sites More sharing options...
Plymouthy Adams Posted May 10, 2023 Report Share Posted May 10, 2023 throw in the towel but do not throw in extra rubber bushings.....you may need what is referred to as a chevy wrench for bolt extraction....yeah these do rust....but before slamming them with blunt force, heat them a few times with the torch....don't have a torch....your headaches are just beginning....

jgreg53 Posted May 10, 2023 Report Share Posted May 10, 2023 (edited) I finally had to drill them out. I'm actually using a rubber boat trailer roller to make my own mounts. It works and is a lot cheaper. So I have enough to add bushings to the firewall corners.. and I tried the torch. Didn't help. It did set the old rubber on fire.

Plymouthy Adams Posted May 10, 2023 Report Share Posted May 10, 2023 you will placing the body in stress IF you add rubber bushings to the firewall mounts...this is your alignment points...and while I think the boat rubber roller may be a bit hard for the body bushing, they should be easier to turn on a lathe for the proper centering protrusion so to prevent shifting. Do not forget to properly torque your body mounts. Quote Link to comment Share on other sites More sharing options...
DJ194950 Posted May 10, 2023 Report Share Posted May 10, 2023 Cannot say for sure on the 1948, but the 1949 and 50 Plymouths did not use rubber under the front-most body mounts! Found it hard to believe for a while , but when I put bushings under the front legs of my 50 Suburban the doors could Not be properly aligned, needed to be removed. Distorted the door opening.

jgreg53 Posted May 11, 2023 Report Share Posted May 11, 2023 Thanks for the advice. I didn't put bushings in there. Quote Link to comment Share on other sites More sharing options...
