Plymouth satellite Rear End Noise

[Beforwarned]

my rear end makes some weird noise when i give it gas or let off the gas. Any ideas on what the problem could be?

 

[5.7 hemi]

Well lets run down the list of possibilities. Brgs., to much back lash, to little back lash, not enough fluid, wrong fluid, axle brgs, worn gears, am I missing anything?

5.7 nope you covered it....Beforwarned...could you be a lil more specific in ur discription..weird noise..a whine, a clunk, a grinding sound, a roar....lions tigers or bears????

Also what is the last three digits of the casting number? 741, 742, 489 are the choices. Pop the driveshaft off the yoke and see if there is excessive play in the pinion. A little rotational backlash is normal but nothing side to side. If the pinion bearings are loose (lack of preload) that could cause the gear mesh to change under load and likely make noise. If you have a 489 case and someone R&R'd the yoke at some point that might be a reason it's loose or otherwise not right.

sounds crazy , but check the hub/center of wheel for fitment, sometimes after market/repop wheels don't seat properly and create an issue , even when the lugs are tightened , ask me how I know

I was having a strange clunky noise which I thought was coming from the rear end. Turns out my tranny mount was shot as and my drivers side motor mount was completely dry rotted and sheared in half. Replaced those an no more noise, so check those too!

Just finished a 71 Buick GSX, full nut and bolt restoration.. reproduction rims, the centers are slightly undersized for the hubs .. so even when you think they are tightened down, they aren't fully seated .. makes a scary sound .. kinda like the back half of the car is going to fall off ...
