squealing/clanking

[slab42]

I have a wierd squealing noise when I am accelerating (even slightly) and I get a clanking noise sometimes from a dead stop. I am also getting driveline vibs at around 70. I thought it might be my U-joint, but the DS has no play in it. in fact when I try to turn it, it seems like the diff is where the play is. I am gonna check my fluid in my diff, but anyone have any other ideas?

Ok, I just went out and checked the fluid, the lower half of the diff cover is wet, but I am not missing a drop. I was on level ground, and a little started oozing out when I pulled the plug. Yes, John, it smelled terrific! The jeep has been sitting for hours, so I have no idea what it is, but it is definitly coming from the back half of the heep.

If you have a crackling noise at dead stop and a squealing noise when acceleration, could it be the CAT? Just an idea!

Well... I hope it smelled good! did you get any on you fingure, cause I would like to smell your... never mind.

What color is the diff fluid? Nice milky color? I would replace anyways, that time of the year I guess! Also, consider brakes, and even if your drive shaft has no play in it, does not mean that the U-joints are goon. I would also change those, they are cheap enough and take only 1/2 to change if your taking your time! The clacing could mearly be the Needle bearings rolling around, still tight but no lube.. this will lead to breakage faster than women run from you!
