2011 Pro-4X 110k miles. New to me with no service history.
Ok, so I changed the engine oil, oil filter, automatic transmission fluid, transfer case fluid, front and rear differential gear oils, and coolant. Everything looked good, except the front differential oil which was sludgy and a lot of fine filings on the magnet.
Took it out for a few miles to get it up to operating temp for final engine oil and atf level adjustment, and to work the coolant through. Heard new whining noise on acceleration only. Sounds like a vacuum leak. Did I knock a vacuum line loose somewhere? I'm just hearing about the timing chain thing, and I hope it's not that.
