front left noise metal on metal

[drcoffee]

I need some ideas on where this noise is coming from. Definately suspension/driveline. while driving, if I let up on the throttle I hear a chirp. when coasting or steady throttle, no noise. accellerating either from stop or while rolling, I hear the chirp. I'm thinking CV joint. It seems to be related to force being changed by throttle on/off. With the van parked and bouncing the left fender up and down, its quiet. Lastly, if I accellerate while turning, there is no noise.

Thanks,

What year, how many miles on vehicle???

Possible wheel bearing. How are the boots on the cv joints??? Could it be the wear plate on front brake pads? Hard to tell without hearing.

Try putting on jack stands. have someone help you see if you can determine where it is coming from.

I forgot the obvious details.

I've had wheel bearings fail and they tend to get loud over 40mph. This sound is just momentary with a sudden change in load to the wheels. I even hear it when I shift from Drive into Park in the garage.

The boots on the CV joints tore open back at 80,000 and the boots only were replaced by Mercury. I suspected that I would need CV joints down the road but don't CV joints clunk and get worse in turns?

Resent repairs: front motor mount, VSS on transmission and new front tires at NTB.

The thing that is puzzling is the fact that you hear it when you shift from drive to park, which makes believe it is a cv shaft. Have you checked the cv shafts for an movement by hand and yes the bad shaft I had in the 94 clicked when turning. Could it be the hanger bearing on the passenger side cv shaft?

That's a term I'm unfamiliar with. What's a hanger bearing? The sound seems louder from the driver's side.

Hanger bearing was more commonly used and rear wheel drive driveshafts, it is a bearing supporting the shaft usually in the middle of it.

I was thinking there was one on the passenger side but if you look in the AX section of the FSM it will show that on the passenger side ishas a bearing support at the transaxle that could cause a problem. Sounds do travel so it could be discieving.
