I have a 06 V8 RWD Sport Edition and when I changed my diff oil I did notice the humming noise (might be coincidental) and same condition as you mentioned. As each day progressed, it got worst..turned out..had to replaced the differential assembly..$1200 poorer
I'm thinking of changing my shift knob on my 07 4Runner Automatic. Question is how does one remove the current shift knob?
I tried twisting it and it would not go.
TIA!
I did not notice any noise at all..although the engine is runner and I have not stick my head in the engine bay to listen to the noise, but will notice if any noise coming out from the ballast
My Extreme HID kit arrived over the weekend and I installed it. Very easy to install. However, the hard part was how to bundle up the wire harness that came with the kit.
Overall, the kit was VERY easy to install and I love the white output!
