Question about 1996 Jeep Grand Cherokee
I replaced my tension pulley and idler pulley and the belt 4x and it still has a squeal. what will cause this?
Look at the pulley coming off the crank shaft. If the thrust bearing is going bad or is bad you will have excessive play in the crankshaft that causes excessive deflection of the belt. If it's this your looking at an engine rebuild. Just went through this on my dads jeep.

I might not have enough information but the squeal is most likely a worn bearing. Try to isolate it with a "mechanic's stethescope" to locate the source. A pin point shot of WD-40 at the whining bearing (NO NOT put it on good bearings should TEMPORARILY quiet it IF it is a bearing. DO NOT overspray, just at the center of the pulleys...the lubricant should get pulled into bearing to confirm that the pump (power steering would be my guess) needs replacing.

Did you take the time to clean all pulleys good with brake clean or similar cleaner, when belt was off? . Sometimes a little antifreeze, or windsheild washer antifreeze can get spilled on the belt(s) and cause that, as well as an oil drip. Take a flashlight & double check that you don't have oil dripping down on there somewhere. Only other thought is that maybe power steering pump working too hard or alternator on it's way out, causing extra load on the belt.
