Known vibration issues?
Hi all,
Need some help in trying to track down a vibration issue. Not steering. But, idling in gear and driving. I feel the vibration through the go pedal and floor board and seat on driverside.
Checked obvious points. Down pipe, complete exhaust system. Motor mounts, tranny mounts and steering.
Got to be some other spot I'm missng. Checked driveshafts. Everything seems OK.
Any help greatly appreciated.
Thx

Well you only really have two rotating assemblies when stopped.
The engine and all it's accessories and parts of the transmission.
I would first look at the engine and the injectors. Do you have access
to anything that can do an uncompensated power balance test?

No I do not. But I did notice a little black smoke as I was accelerating onto the hwy. Going to need to do a injector buzz test.
Noticed while coming home truck seemed bog down a bit at low speeds.

Get an app for your iPad lik Forscan and a wifi adapter. Then use it to look for misfires. It helps identify the cylinders causing the issue.
Could be an injector sticking internally and a buzz test doesn't really pick that issue up.
