My '97 Land Cruiser lifted on 37s with a brand new OEM pump and OEM steering box steers like a 911 compared to my new IG. The IG has zero excuse for the slow return to center, wider turning radius and movie car steering corrections when a nearly 30 year old truck can do everything better in the steering dept.
My local Pasadena dealer service rep told me the squeal needs to exceed 90 db to be considered for a warranty replacement, but even then there are no guarantees that the new pump will be silent.
I conjecture that IA knows there is no fix except to go back to the supplier and ask for an entirely new de$ign. This is why they're dragging knuckles at our expense.
I've come to accept it (begrudgingly) because I'm not dropping $3K on a new pump plus labor to end up back at square one. I'll give the min level cold a try because max level cold made zero difference on mine. There's split bro forum science here whether high or low fluid level will actually eliminate squeal. Make up your mind internet. lol
Let's keep this thread going with more owners voicing their displeasure. Rock on!
