Power steering pully?

Has anyone ever have their power steering pully explode on them? Easy fix after replacing upper radiator hose and liquid steeling the holes it put in my radiator? Have just never seen or heard of this? Any explanation of why it would have happens would be nice. Btw I have a small leak in power steering pump on the in hose to the pump. But nothing more then a drip a day maybe, took me months to notice it.

96-98 has a plastic pulley. I had one come apart that was only a few years old. Be very careful when pressing a new one on, I ended up with a hairline crack from trying to hold it from turning while I pressed it on.

You can replace it with a metal pulley from a 93-95, but you need to get the pump mounting bracket from a 93-95 also for it align with other pulleys correctly.

It only took me 30 min to replace with a manual socket press. But its nice to know you can replace it with a metal one thanks for the info.

It's a fairly common issue on the '96+ Jeeps and Dodge trucks for the plastic PS pump pulley to either crack, or even self-destruct to about gazillion pieces.

Yeah, they do that.

I carry a bypass belt, but the steering box is unappreciative.

You can switch to the metal ones from a first gen if you steal the pulley and bracket from a first gen. IMO, I'd rather have the pulley break. When they're 19 years old they break because they've gone brittle, but it takes the pump stalling to do it. The pump shouldn't be stalling.

Why would you rather have the pulley explode over having a metal pulley?

Would this work with a metal pully??

http://m.ebay.com/itm/111616502950?r...&ul_noapp=true

Will a PS bracket like this work with a metal pully from a 95 on a 98? I'd like to fix both issues at the same time.

Because if the pulley is exploding, something bad has happened to make the pump stall. I'd rather have the pulley explode than the pump destroy itself.

Basically, it's a fuse.

And it doesn't do it if you have a properly working steering system. The pulley blowing up is a symptom, don't treat symptoms, treat the root cause.

Mine crumbled when I touched it while the belt was off but you could visibly see the micro spiderweb cracks in it and it was original so like 17 years old at the time.
They are a composite and become brittle but it takes quite a while.
With the steel pulley you need to add a spacer or washers to line up the grooves.

Would a slow like really slow leak cause it to stall?

Yeah, if you're low on fluid the pump is working overtime. It'll fry the pump slowly.

Is it noisy? They usually complain pretty loud if it's low on fluid.
