2003 Kenworth W900L, C15 cat. Got a loud squeak I've been hunting for several months if not a year. I've posted another thread about the hood shaking and I was thinking the squeak was a result from hood shake. I've pretty much ruled that out. Squeak from what I can tell sounds like it's coming from around the firewall down around my feet on drivers side. I've been over it a lot and can't find anything loose or moving and can't find anywhere that looks to be rubbing that I haven't greased or adjusted. Any of you guys ever have a rear motor mount go bad that squeaked?

when do you hear the squeak?
-
Only when rolling. Especially when slowly moving around on rough lots and on rough roads. It will stop with just the slightest turn of the steering to right. Gets worse when steering turned to left. I know for sure the drivers side rear mount needs replacing. Just wondering if it could possibly be what's causing the squeak. I'm thinking maybe the turning of the steering wheel is possibly flexing the frame rail just enough the stop the squeak or make it worse in the other direction.

Anyone got an idea of a ballpark price for the rear and front mounts/bushings?
-
Maybe hunt spring bushings, pins, hangers, and loose u-bolts for a while.

I think about $500 for motor mounts but will have to dig thru receipts. What about the bushings where your stacks attach to the cab?
dirthaller Thanks this. -
Are the rear motor mounts a huge job to change? Fronts look pretty simple. -
Try a little spray lubricant on the little rods that go throught the bushings on your stack mounts ( near where the tailpipe goes in to the ugly piece under the heat shield......by the top of the door ). Then some grease on all of your hood catches before you start throwin parts at er.

Spray lube everywhere hood touches cab then drive around to see if it makes less sounds?
-
My 07 W9 did that and it was those rods (aerocab)
