Trailing Arm Bushings "Revisited"

[72bowtiestepper]

I read a lot of the older posts on here about the debate on using poly trailing arm bushings vs. the stock type rubber ones. Any of you guys that have replaced your rubber one's with the poly have any issues after a few years of driving ? I have heard of squeaking problems and not enough flex with the poly.
I have my arms removed for repair, and only want to replace the bushings once. Thanks in advance for your input !

I'm not sure it really matters after looking at the stock trailing arms. They are so flimsy, I'm sure they flex alot.

I know what you mean.....I just finished reinforcing mine in the area where the u-bolt attaches to the axle. Welded in some 1/8 plate to "box in" & strengthen the area that was getting rusty. I'm sure they were designed to have some "Flex".

I've used poly bushings w/o issue. My 68 had them in place for 6+ years of daily driving & they were still good when pulled from service. My T/A's were also stitch welded along the length of the seam as wel as boxed in (front & rear) to increase strength.

There was more bind vs the rubber lined steel sleeve OE bushings & non reinforced set-up but nothing that was overly concerning based on the condition of the poly bushings after the 6yr period.
