47windsor Posted July 10, 2015 Share Posted July 10, 2015 After going thru the repair bills from the previous owner I noticed a sizeable invoice for replacing the upper & lower trunion? Would this be the same as upper & lower control arms on the front end or? Thank you in advance for any info on the Trunion. Bruce Watson Link to comment Share on other sites More sharing options...
Guest Bob Call Posted July 10, 2015 Share Posted July 10, 2015 The trunnions fit between the control arms and the spindle allowing the control arms to move up and down and the spindles to rotate at the same time. Trunnions were replaced by ball joints beginning in the late 40's and early 50's. Link to comment Share on other sites More sharing options...

Rusty_OToole Posted July 10, 2015 Share Posted July 10, 2015 Trunion was a specific kind of suspension used by Rambler and possibly a few other makers. Chrysler used a king pin arrangement which is a little different. They spoke of king pins and spindle supports. Not trying to be picky, just pointing out why you won't find "trunions" in your Chrysler manual. Except, they did use ball and trunion universal joints for extra added confusion.

47windsor Posted July 11, 2015 Author Share Posted July 11, 2015 Rusty, Once again thank you for your input & information---- I have had mostly vintage GM cars in the past & wasn't familiar with the TRUNNION & where it fit into.
