Hard turning left

Check the power steering fluid. If it is low or dirty, fix that first. Check for leaks, especially on the actuator cylinder seal(s).

If the fluid is good, you'll have to find out what else is causing the power steering system to drag on the engine. This could be a problem with the suspension that makes left turns hard (worst case is a part that goes out of alignment due to a rusted-out attachment point).

First get the code that set the MIL Lamp. Will most likely, point to ABS Wheel Speed Sensor or System.
Then have the system diagnosed and repaired

Hi the steering lock could be causing you the problem try turning the steering wheel hard left whilst turning the key and do the same hard right.

it may be hard to turn but you should find once you have moved it slightly it will unlock allowing you to turn the key so dont adjust the steering wheel turn it to the right as if your trying to turn to the right and if this dont let the key turn turn the wheel to the left it only needs to move slightly to allow the steering lock to free the key,

doing the above should solve you problem

give me a shout back if you have any further problems ok

The rack and pinion needs to be replaced to rectify the one side turning easily and the other side not turning so easily. It's like a flapper in the rack and pinion, I think.

There must be enough pressure built up by the power steering pump if it goes easily at a stop when one turns left.

sounds to me like front half-shafts outer c/v are frozen OR the c/v boots are split and the lube is gone.
a visual on the boots, if you see grease all spread around there, then the joints are worn.........buy new half-shafts.
also, possible worn ball joints causing the steering knuckles to bind on a hard turn...

i have a 2000 chevrolet silverado truck that the tow/haul light keeps coming on and going off and the tow haul engages without starting it.

the hyrdo booster is bad has a interanl leak it is part of the or i should say is right behind the master cylinder

it could be your steerig box.some of the f150 and ford bronco and F 250had the same prolbem

possible wheel speed sensor problem. need to check codes and data with proper scan tool.

Sounds like it was pulling before the brake job...if so the only thing you didn't replace was the rotors, I assume you turned them? and did you see hard spots on the rotor? discolored area that didn't cut the same......switch the rotors left to right and see if the problem moves or just replace them if they've been cut twice.
