Subframe problem?????

[68camaroguy]

So i had the subframe bushings on my 68 camaro changed but i dont know if they were done correctly, the car seems to shake at above 60 mph. sometimes it doesnt shake, but when it does its bad. any ideas or suggestions as to what it might be???

Did you have them replaced with new stock rubber bushings, or did you switch to some poly bushings?

If you went with a stiffer bushing (like the poly) it may cause more vibration throughout the car.

are you sure it's the subframe bushings doing that, have someone follow you down a road, to watch the car, mite have something else wrong you don't see. make sure car is straight on the road not crooked. with the new bushings in now other problems mite come up that now the body is stiffer. good luck.
