Hi Guys,
I've disassembled the rear of the bumblebee and the control arm pivots and bushings look to be in good shape. My plan was to blast and powdercoat the control arms, which would require removing the pivots/bushings (due to the heat)...but I hear re-installing these can be a beeotch. And I generally prefer keeping as much OEM as possible. So...do you think it's worth leaving the bushings and pivots alone and just painitng the arms? I'm aiming for this bumblebee to be a solid #2 car when done. Thoughts? Thanks! |

Unless bushings are showing signs of dry rot, cracking, or having become delaminated from the trailing arm, I'd leave them OEM for a street car. Photos of your parts look pretty good. I wish I had a set like that! Mine are chunked and cracked. I'd really like to find a decent set of arms rather than rebush mine. We'll see what turns up before I need mine done.
The OEM bushings are vulcanized into the trailing arm and will have a torsional, lateral, and longitudinal spring rate to them. Replacment bushings will never be quite the same and cannot duplicate that rate. Nothing against aftermarket bushings since in some cases, it simply can't be avoided. Same for track use - there are advantages to changing them. Once you veer away from OEM, you end up in all the other debates: Rubber vs. Urethane vs. Delron vs. metal bushings (like self oiling Bronze) vs. needle bearings and/or spherical heim joint solutions all of which have their Pro's and Con's both for ride & handling and NVH. |
