Suspension Troubleshooting

Replaced the top bushings only (both left and right) with urethane bushing and SRC started to work fine without tripping the code.

Where did you get the new bushings from?

I spoke with Captain Z CNC today on the phone about my SRC issue. He recommend I check to see if there is any play in my actuator gear(checked out fine) using a screwdriver. After that checks out then measure the height of the gear from the top of the cup. This measurement should be 5 MM. Driver side is 6 MM, and the passenger side is 7mm. I'm not sure what the tolerance is, if any for 5 MM. Does anyone know if this is listed in the FSM?

I got the bushings from energy suspension but can't find upper front shock bushing on their website for some reason. However, Eckler's seems to have the same.

Last week I had to jack up the passenger side of the car to re-route the O2 sensor wiring. This morning I started up the car and it appears the SRC light was out, but after driving down the driveway it came on. This gives me the feeling that it is jamming up due to the bushings. I may try and replace those bushings to see if it works better.
