Before I do this I need to ask a stupid question. But first, from what I've read the backup lights are controlled by a switch screw into the transmission. Its's said to comprised of a spring and a little steel ball I should not lose . Also need to mention the I've checked the electrical connections and all are good. Just no signal from the switch. Now the question. Will removing this switch (since it's screwed into the trany) dump the transmission fluid?

Thanks for the input BlueCuda. If it is in fact a bearing issue I'm kind of screwed in that I don't have any place to do that level of work and that leaves me with having to go to a mechanic (uhg🥵). Same would be true if I had to do any work on the diff.

It tock a while but I finally Got the rear of the car up. The only noise I heard was a slight scraping on each wheel which was the brake pads. Nothing else. As EDDE mentioned, The tires in the rear are new (not the most expensive rough $75 ea) I'm starting to think it could be them. Short of cracking the diff cover and draining the grease and resealing and refilling. I'm stuck. Not willing to replace new tires with more expensive ones on a hunch. I appreciate everyone's input When the rare tires where and I have to replace them I'll then look at slightly more expensive tires.

Thinks for all the info everyone. The only thing I can add at this time is when driving and swerving right and left no change in the sound level or pitch. Don't know if that helps narrow thing down. But I'll try to get the rear in the air as soon as possible

Noise can be heard clearly starting at about 20 - 25 mph and just gets louder after that. Never deafening but loud enough to be annoying and drowning out the radio LOL

A while ago I started to notice a low frequency rumble coming from the rear. It's not RPM related. seems more speed related. Faster equals louder, take the car out of gear RPMs drop sound remains. Bring the car to a stop, sounds stops gun the engine in neutral engine roars but no rumble sound. Thant's all the detail I have. As always any and all responses are appreciated.
