[QUOTE="SammyAE86, post: 450073, member: 23891"] Im looking for help to diagnose a noise from the transmission. Its a 2003 wrangler 4.0L 5speed manual. The noise is subtle on lower gear, so its getting louder on 3rd and 4th gear, loudest on 5th. If i release the accelerator, the noise disappear, its louder when i try to maintain steady speed on the highway at around 90 km/h. I lifted the truck on 4 stands to isolate the sounds, and its a 100% from the transmission, so no diff, not the engine, not the t-case. I replaced the release bearing and transmission oil 2 yrs ago. i looked inside the tranny and there were no sign of damage. The sound was present prior to the release bearing replacement, I replaced it cause it was split in 2, I thought it was the origin of the noise. Im thinking of input shaft bearing, but i dont want to remove and reinstall the transmission just to try it :LOL:. It got around 180 000 km (so i guess 110 000 miles). [/QUOTE]
