2006 Z71 here. I've started to get a knocking sound from what sounds like the front drivers side during a slight turn to the right. You can't feel it in the steering wheel but you can on at the pedal and you can hear it. However it only seems to be when its cold. Once it warms up or you have been driving for a while it goes away. I've checked the front drivers wheelhub and its tight..no play. I've looked at the rest of the suspension partsand they look fine, even changed the sway bar links just in case. The I-shaft is tight also with no play. I also changed the brakes but this was happening before then. suggestions? oh and new shocks so those are good and tight.

i double checked the hub and there is zero play in it. I did notice some play in the pitman and idler arms, could that make a knocking sound with a slight turn of the steering wheel?

CV shafts maybe. I'd check 100% of the steering and suspension thoroughly. Check the left side, not just the right

Check your torsion bar bushings. Right under the drivers door. Grab the torsion bar and shake it up and down. Shouldn't move at all. I have replaced a lot of these. I just helped a guy on a different post with this. Let me see if I can find it.

      New or used

      I prefer new, but not without a deal. Historically I've bought severely aged new inventory, leftover model year, unpopular configuration kind of stuff that sits around on dealer lots until they just want it gone. $10k off MSRP kind of stuff on a mid-priced truck. That really, really helps knock down that first year depreciation. It also requires being somewhat flexible on colors and options. I wouldn't buy a 4 cylinder if I was looking for an 8 cylinder, but if I got blue paint instead of black, or a great deal was lacking a minor option, I'm willing to overlook those things for savings.   Used <> used. Condition and history are everything. If I'm buying used I'm looking for cream of the crop. The truck from the guy who religiously pampers it, and then decides a year later he wants newer and nicer. NOT the ex-rental vehicle, or the crew cab traded in by the family with 7 kids who like to throw food, and the oil only got changed when there was time long after the oil life monitor started alerting.

      OCI, not when but why?

      @Grumpy Bear the conclusion from your post about doubling engine life has me curious. Are we literally talking an expected life of 250,000 miles potentially becomes 500,000 miles with a step up in filtration for fresh oil at "the oil factory" when it's bottled? I know you said that's a single variable among many, but, that's significant if the implication extends that far into a real world use case. I would think the oil marketing folks would really eat that up and make it known.   Particles introduced during oil change is a fairly easy one to avoid, but probably not intuitive as one would think. I.e. using a clean funnel. But...what was it wiped with? Paper towel leaves behind little fibers. A solvent if not dried is not something one would want to introduce into their engine with clean oil. And, keeping the oil filler neck clean and free of buildup.. Look at some guys engine bays and they're an absolute mess. Some say that's better than the drawbacks of cleaning it. I'm not a buyer of that idea.   I've also wondered if "flooding" the top end of the engine with oil while filling is a bad idea. During normal lubrication the oil flows in a gutter back into the galleys. But if you flood the area you're potentially washing the top of the rockers, springs, and other areas which may not get much oil wash normally, and you're mixing all that into the new oil. I just don't have the patience to pour slowly. 😆

      DTC P2C48 auxiliary cooling pump

      By Newduramaxh*ar · Posted

      It was a bad pump, i had a dealer next day the pump. Gm part #86591535. Tools needed 10mm socket, pliers for hose clamps, 1/2gal of Dexcool. About 30mins to remove and install, pump located near oil filter on driver's side frame rail. I had a local mobile mechanic delete the code, he had a snap on scan tool. My scanner could not delete the code. I drove back home about 700 miles since then, and no check engine light. Hope this helps someone in the future in the same situation i was in. Thank you to all that helped me.

      Hi Gary, I guess it all boils down to personal preference and what you can afford. I, personally, buy new because I will know from day one how the vehicle is maintained and driven.
