I am having steering issues with my 2006 F150 STX 4.6L. I have noticed at low speeds it seems that it is harder to turn. About four months ago I rebuilt the whole front end with the exception of the rack n pinion. When I am driving at highway speeds it doesn't seem to be an issue and I don't get any excessive noise from the engine compartment. I checked the fluid, and it is at the proper level, and I couldn't find any leaks. So, I am wondering if the power steering pump is getting ready to go completely out or if it could the rack n pinion I didn't replace. Any help would be appreciated thanks

 

have you checked the steering shaft itself ? the shaft ujoints get corroded. makes it harder to turn.

 

i took your advice and the steering shaft and Ujoints seem to be in good shape

 

I would then check the rack and pump for obvious signs but, you say the fluid level remains good so...

 

How many miles on the truck? Are the tires "normal" sized?

 

yes tires are normal size...matter of fact just got them in February......268000 miles

 

I suspect it's power steering.
