LS4 Performance - '07 Impala SS tune up questions

I am going to be replacing the power steering pump on my Mom's '07 Impala SS as well as changing the plugs. My question is to you think it needs plug wires too? It has 105k on it and the wires seem to be ok, they aren't really much wires anyway. Any tips on changing the plugs I should now before getting started?

The plugs and wires are supposed to be changed at 100k

Alright, I just wanted to make sure they needed to be done before spending $80 on them. Thanks for the advice.

That for plugs and wires or just plugs?

Just plug wires, plugs were about $45.

Ok cause you will need to do both

yeah, you'll definitely need to do new wires too, because you will destroy the existing wires trying to take them off, haha... have fun!

haha thanks, you make it sound like such a fun job!

Well got the plugs done today, man they sure make these things fun...

When changing plugs in the 5.3, are you able to tilt the engine forward like in other FWD GM vehicles to access the rear plugs?

Not much, maybe 2 inches. I removed the dog bone and had someone help me rock the car forward and locked the parking brake when it was forward, that gave me just a little extra space to get my hand behind the engine. You can't see anything back there you have to do evereything based on feel in the back.

With the FWD you could remove the dogbone then use some tie-downs and clamps to wench the engine closer to the front. Needed to disconnect the air filter inlet to the throttle body. GM made a tool for this but was cheaper to wench it
