96 Suburban vibration, rear differential?

more common in the front, but when you turn, the outside wheel bearing that turns faster makes more noise if it is going bad. have to pull the axel. but might be other bearings. old john

Sounds like ring&pinion, OR axle bearings. (could be either) The turning left WILL load the axles and the noise could be being generated from either source.

- 1 - Put it on jackstands and use a stethescope.

- 2 - Pull the differential cover and take a look inside.

or..........try this........

I'd loan you mine, but I'm a bit picky with my tools.

any whoooo....... it's a minor deal to look inside the diff. cover and see what kind of markings are on the gear set and what's maybe laying around in the bottom of the housing.

let us know....

It is not the ring and pinion because it would not be effect by turns. My first choices in differentail and second choice is maybe wheel bearing but being that they are full floating it does not sound likely based on symptoms

I am sorry, I meant to say semi floating axle that float on roller bearings at wheels that absorb no side thrusts as the axle is held in by a C clip in differentail.

What does the C-clip lock the axle into?

Take a look - >

Sometimes a picture is worth a thousand words.......

====== ====== I didn't need a picture.........

I needed you to tell me that they're clipped into the planetaries.

but you didn't.

now.... I've got to find another way to get you to help me to get you to say that side loading the axle may apply presure to the ring gear.......mmmmmmm......let me give it some more thought.
