Clicking Noise When Coasting - 91 Ls


blessed

Recommended Posts

Hey guy's,

91 LS, 200k miles and noticed a clicking noise when I let off the gas peddle. The noise goes away when excellerating and returns when I let off the gas. Anyone have ideas or suggestions?

This has been happening on and off now for over a year. It happens mainly after the car has been sitting at an idle for a while (5 or 10 minutes). The clicking noise seems to click with the speed of the car. Clicks slower as the car slows down.

I'm thinking it's the drive shaft or the u joints or other bearings tied to the drive train. I don't think the LS has CV Joints but not sure. If you have any links to how to replace any of these please let me know.

Thanks!

Yee, the LS has rear CV joints. They are not easy to detect a bad one as the normal FWD car clicks badly when you make a sharp slow turn. Grab them and move them in/out and up/down, You may feel a bad one. Half-shafts (what they are called) are pretty cheap to buy in a reconditioned state.
