Not sure if related to this, but they did start on the same trip. The Blazer is making a popping noise when making left turns. It only seems to happen when they are sharp turns and sounds like it is coming from the front drivers side. It won't pop when turning, but instead pops when starting to straighten out. No idea where to start with this, and don't have much money to throw at it. Going to grease every joint I can find when I get home today to see if that helps.

It isn't very loud, thought I was just driving over a man hole or something at first or just hit a slight bump. But it can be triggered fairly reliably when straightening out on a sharp left.

Note: The only time I hear this is with sharp turns. Making a left turn on the road I won't hear it (could be covered by engine noise). I only hear it when I'm making a sharp left turn, like a left at a red light/stop sign.

 

is it 1 single pop or does it keep popping the whole time your turning

 

If I remember correctly it popped multiple times. I can't move it right now (have to replace diff cover) so I started it and spun the wheel all the way right, and then all the way left and listened for a pop and didn't hear anything. Maybe it fixed itself? Or I need to be moving for it to trigger.

On a side note, I was standing outside of the Blazer and noticed when I had the wheel cranked right or left that the front end would fall down some. Is this normal, or could it be connected to the popping?

 

most likely you have a bad cv axle the vehicle would have to be moving for it to make noise

 

This?

Are there any test I can perform before buying it to be more certain? Could I just put the truck on 4 jack stands, put it in 4WD and "drive" it while turning to see if it pops?

Also can't find one on rock auto for my Blazer that has ABS. All the Surtrack have no abs ring, and the Cardone Select have no mention of it. I remember doing the hub assembly last year and don't remember having a ring on the CV Axle. Thought ABS was internal on the hub itself.

 

Yes jack up the front tire off the ground, grab the tire top and bottom then alternate top bottom push and pull while feeling for play. Have somenone look at the hub axle connection while youe doing this and and have them look for the axle shasft to move up and down indicating a bad hub . most bad wheel beerings will have an ABS light on also hears a vid to help you check

 

After driving it to the shop for other reasons I was able to pay more attention to the noise. It would seem to be one pop when making the sharp turn and one pop when straightening out. Both pops require a very sharp left turn and it would seem I need to be moving as I can not replicate it with the car standing still.

I should be able to perform the bearing test tonight.
