f1ss Posted May 10, 2011 Report Share Posted May 10, 2011 When you turn can you feel a little knock on your steering wheel? Sometimes it can be heard more so than feeling it (in the steering wheel). Quote Link to comment Share on other sites More sharing options...

Contaminates left from not flushing steering system? That would kill a new pump. Quote Link to comment Share on other sites More sharing options...

paulguy Posted May 10, 2011 Report Share Posted May 10, 2011 I would just use compressed air myself, and add a filter on the return line for some insurance. What is wrong with the pump, what is it doing? Quote Link to comment Share on other sites More sharing options...
jswc61 Posted May 14, 2011 Author Report Share Posted May 14, 2011 ok i changed the pump and it works alright but it seems like the pump dont have enough power.... like when im just sitting there idling its really hard to turn the wheel... what do u guys think... is it just another shitty pump Quote Link to comment Share on other sites More sharing options...
paulguy Posted May 15, 2011 Report Share Posted May 15, 2011 (edited) Could it be a bad steering wheel speed sensor? Or pressure control valve? Document ID# 1653246 2002 GMC Yukon Lack of Steering Assist or Shudder During Parking Lot Type Maneuvers - keywords bind booster brake hard hydraulic low no noise oil power slow speed steer trailer #PIT3386A - (Apr 28, 2005) Lack of Steering Assist or Shudder During Parking Lot Type Maneuvers 2002-2005 Cadillac Escalade, Escalade ESV, Escalade EXT 2002-2005 Chevrolet Avalanche 1999-2005 Express, Silverado, Suburban, Tahoe 1999-2005 GMC Sierra, Savana, Yukon, Yukon Denali, Yukon XL 2003-2005 Hummer H2 The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in the PI. Condition/Concern: Some customers may comment on a lack of steering assist or shudder during parking lot type maneuvers. Recommendation/Instructions: Please follow normal diagnostics in eSI for this condition. If the customer situation warrants a repair, replace the current pressure control valve with P/N 26095470, available from GMSPO. This valve will provide additional steering assist during parking lot type maneuvers. If this concern occurs when stopped or at very slow speeds with brakes applied, please reference PIT3310. Please follow this diagnosis process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed. GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.
