Build Thread My 1986 T-top Build - Lasting Memories

Why do we keep talking about rubber bushings when you can use poly?

My $.02 on the control arm gig... I ran stock uppers and non adjustable MM lowers on my SN95, and ended up having vibration issues at highway speeds. Once I swapped to aftermarket uppers and adjusted the pinion angle, the vibration went away, but I had more noise in the car from the heim ended uppers. So it will most likely end up being which issue you would rather have... All that being said though, IIRC, you reinforced your torque boxes, so if you dont have a lot of crazy uneven driveways to manage, you could probably go with a set of adjustable uppers with fixed bushings on each end and be ok.
Were the hiem joints intolerable?
 
So, tell me what MM is talking about Allen.

I get what they're saying about binding, but do you have that problem?

Well I'll tell ya, if something is binding back there- other than the engineered in bind- I can't tell, but keep in mind, I'm not using weight jacker lowers either. Just plain ol solid.
 
I wouldnt say they were intolerable. You just had more rear end noise than when the car was stock. With as nice as you are making Doby, I just figure you should stick with rubber or poly bushings, especially with your mild engine set up.

From what I read, the poly bushings tear or have too little flex to keep from twisting up torque boxes. But like I said above, I bet since Dave reinforced his that he would be ok, assuming he doesnt have a 55 degree slanted driveway to conquer every day twice a day.
