I have a creak sound that has become apparent and after a week I still haven’t confirmed it’s origin.
Here’s what is observed: a unmistakable creak after a 20-30 minute drive and is only heard at low speed less than 10 mph roughly. At startup and first 5-10 miles of rural driving /stop and go, and bumps at slow speed it is quiet. Rolling along at idle speed in a parking lot and gently accelerating will produce the creak momentarily ( engine torque). I believe under constant load at drive speed it may not be creaking and for sure it can’t be heard.
Suspension history:
Currently it has 164k, I’ve put 2k on it in the last 2 months. The LCAs were replaced under recall at 118k and at 161K PO had a very reputable frame and alignment shop do an alignment and suspension check which presumes the suspension is in reasonably good shape. (Qualifier - I took my truck in for an alignment at the same place and they checked suspension and wouldn't continue until I replaced the worn out parts - speaks to their mode of operation). I’m pretty sure the suspension is in good condition and personally I can’t get any movement in joints with wheels off the ground.
Suspects:
This leads me to think it may be a motor mount, like the right motor mount near where the creak is heard. And it seams to be heat related shows up after 20minutes of driving) of which the motor mounts would see a change in temperature after 20 minute drive.
Any thoughts on potential
suspects?
Is their a way to lube the right motor mount in case a subtle flex of the rubber is causing this internally? Looks like I could dump soapy water on it and it may deep down around the rubber inside?
One other suspect is the top mount of the right front strut, but it doesn’t seem accessible for inspection without complete removal. Is there any way to rule this out?
Sway bar end joint?
thx for any thoughts on this in advance!
I did read the sway bar end could produce a creak.
