Power steering pump

If ye ever need to change yer pump at any point and find that ye've got a squeel and judder on full lock after renewin' it )and bleeding it through properly).. chances are the new pump might be knackered!
Having just changed mine, ah found ah had these problems but another new pump soon sorted it out

Just about to tackle one in a 110. Pump is leaking oil all over the shop. Can this be fixed with new seals or is it a common prob that needs the pump replaced?
I am a complete novice so feel free to treat me as such!!
Cheers.

Mine squeals like a pig on full lock are they hard to replace on a defender 90?

Easy on a fender just a few bolts to undo, you know the ones where you need to be a contortionist to get to them! I found it easier to do it from under the vehicle. Let all the fluid drain overnight though

Hoping to buy a new pump this weekend but mite be next weekend when i fit it
