I have just over 200k. Is there a way to check the pump for broken vanes?It could be the pump but I'm leaning towards the internal seals failing in the rack n pinion allowing PS fluid to move freely from side to side which means no PS. Vanes in pumps do fail but not often.
How many miles on the truck? Mine started to show some seepage around the boots just north of 200k, but it's still working, just added it to my to-do list.
