This is just a guess. check the carrier bearing by jacking up rear at the rear-end and have an assistant get in start and shift into gear have foot at ready while you peak under you should get a sense of direction of where the noise is coming from.
if you need help with something else just reply back.

Testimonial: "Thanks Mark. Been diagnosing driveline issues like that all my life. This is not like that. The noise and vibration are unique.Changed tires and that helped somewhat but the drone noise, although diminished, remains."

My 2000 gmc Jimmy will not go into the parking gear also I have to start it in neutral plus no check engine light goes on

Sounds like the neutral switch on the column is bad. It should be inside on the steering column by the floor and is half moon shaped.

GMC JIMMY making clunking noise in back

I believe I would carefully check the u'joints first. Get under it with the emergency brake on,the wheels chocked and the transmission in neutral.
Check if there is any slack or movement in in the tube..
I hope this helps. Robert

I am deaf, while driving my Jimmy I would feel a very large vibration in the bottom of my seat and smell something burning. Could that mean I need to replace a converter?

You might have a heat shield that has come loose from your converter, and that is what you feel making the vibration, and the heat from the converter could be cooking your floor boards.

It would be wise to take a look under your truck to see whats going on

Good Luck

Diverter not working, no heat to floor 2000 Jimmy

It sound to me that you have a blending door actuator problem. This video shows you how to repair them. I would recommend that you replace them. Can be a little spendy but worth it in the long run.

Loud Vibration at all speeds

A couple things here. 1.) You either have a tire out of balance. 2.) You need an alignment 3.) You have a tie rod getting ready to go. You can check the tie rod by jacking up one side and if you can wiggle the tire back and forth you have a bad inner tie rod. If you can wiggle the tire (hands at 12 and 6) and wiggle the tire in and out you have bad ball joints. The first two you will need to take it in to a shop and have them check your tires and alignment. Also you may want to have the shop check your wheel bearings. I hope this gives you some direction. Thanks for using FixYa!
