I’m sure this has been discussed before but I can’t seem to find in search engine so here I go.
I recently purchased 2012 Rubicon with 280k original miles. Engine is from 2014 with currently pushing 26k. Transmission has been completely rebuilt and has new transfer case.
I seem to hear slight rattling noise at around 2-2.5k rpm in 2-3-4 gears every now & then. When I push the pedal hard it goes away. Some say it’s normal or “Jeep Thing” but I’m afraid it’ll lead to some technical failure in the future.
Also in higher gears 4-5-6 it has a slight whistling sound.
I’ve been driving manual cars since 90s & to me it doesn’t seem quite normal.
Maybe the guy who rebuilt did crappy job. Idk.
Does anyone have better idea? Help me out ppl.
