The engine or entire truck being replaced? Wow! Crazy they can't figure it out.Odd...my 5.7 is currently being replaced with only 900 miles on it because it sounds like a weed whacker string spinning and they couldn't figure it out. (replaced alternator, oil pump, and timing gear with no luck) Obviously they're different motors and different sounds, but I would have it checked by the dealer.
I'm taking mine in this evening so they can start it up first thing in the morning to hear it. Besides the annoying squeaking, service techs are going to upload the latest and greatest TPMS programming that just became available and any other transmission/engine tuning updates. I'm keeping my fingers crossed. Hoping this doesn't turn into a duel of "that is normal, just live with it" contest. :i_rolleyes::duel:I have a single alternator.
I have not spoken with a dealer yet about it. By the time I am at the dealer, there is no problem to demonstrate. I do not want to leave it overnight just to hear "no problem found, it is normal" the next day and no way for me to disprove it because it will be warm again by then. I would like to narrow it down, if not fix it, myself first but I haven't had a chance to do it yet.
Mine squeaks a bit, thought it was the belt, but I'll check for under the cab noise in the exhaust and report backSo before I take my truck to the dealer this evening, I wanted to have a better idea of where the squeaking might be coming from. So at lunch I pressed the emergency brake down, crawled under the truck, and used the remote start to start the vehicle. No squeaking from the engine compartment...it just purrs quietly. However, the loud squeak was coming from directly under the front doors each side. Scooted my way down and I believe the squeak is coming from a downward bend on the exhaust pipe. There is a sensor just above the bend. The bend is wrapped with some thin, gold/copper colored metal resembling tin foil (heatshield?). As the exhaust warmed up the squeaking went away. Laying underneath centerline of the vehicle I could hear it on both sides, with the driver's side the loudest. Didn't have much more time to tinker. Any ideas??
