Good evening friend download the transfer no, you have to lift the XQ engine when you take the carter will hit you from the front transmission not from the transfer and that pump does not wear oring she has two pine nuts and already that pinions are worn you have to replace the pump I already have experience I advise you change the oil pump so that you do not lose the work or your engine lifts the engine with a crane or lady as they say here in Venezuela. that remove the nuts from the engine bases and the fan protector

Thank you very much friend for the answer with respect to lifting the engine, it is very reasonable to work with respect to the pump this pump is the one used by the Vortec 5.3l and is placed in the crankshaft. since this with the service time deforms and sucks the Technical Bulletin Number 02-06-01-038 since the taquets enhancing to sound to have the working temperature of the engine ..
