| Re: GM Rear Cradle Bushing Torque What maintains the pressure on the bolt has nothing to do with the bushings.
The bushings are a loose fit, as James said.
Inside the mount itself cast into the rubber, is a metal sleeve. The bolt goes through the flat washer and that hits the sleeve on the bottom and the floor pan area on the top. When you torque the bolt the sleeve is tight on the flor and the washer but the bushings just fit into the gaps in the mount to keep center part with the sleeve from moving around.
The Spectre bushings are VERY tight and shouldn't move, but the GM TSB bushings are much thinner and just sit in the holes.
If you suspect the bolts may actually be loose you should check them, but it is normal for the bushings to move. |
