Hey guys,
I'm running 35s with 2.5 inch lift on my JLU sport and was losing my 7th and 8th gear on the highway so decided to switch to 4.56 gears. After I got the Jeep back from the shop, I noticed a "whining" noise at certain RPMs/speed. I put 500 miles on it and took it back to the shop so they could do the 500 mile inspection and change out the diff fluid. The shop said everything looked perfect and that the whine does not have anything to do with the new gears.
So here's my question. What is the whining noise I'm hearing? Here's some troubleshooting and information about the whining and when it occurs.
If I am in neutral and/or park, the whining noise does not happen (even if I hit the gas and raise RPMs)
When I'm in drive, the whining noise does not always occur. It only happens at specific speeds. For instance, if I'm going 45 mph in 8 gear there's no noise, but when I am going ~48mph I can hear the whining.
I just took a $2k mile roadtrip and had no issues with the Jeep other than hearing the noise at certain speeds.
Hopefully you guys can help diagnose. Any information is helpful!
