100k service?

[Bombsquad85]

Hey guys

I'm not gonna lie I didn't search. Sue me....

I have 105k on my 05 Denali and I'm wondering if any of you guys have any ideas on some maintenance I should tackle before an item goes bad. I want to bring the truck back to as close to new as I can a d I plan on keeping this truck for a long time. So far I've done the basic synthetic oil change. New I take. Suspension upgrades (tbss 2/3-4 kit, moog problem solver LCAs, timken hubs. And then just some cosmetic stuff (pm grill, removed racks, hids leds, new bumper lights and gauges.)

I'm more concerned about the drive train right now. It pulls hard and drives smooth but I want to make sure it stays that way.

Any tips would be welcome

normal maint I would think plugs wires and filters. theses motors are great if you treat them good. that's a young engine mileage wise.

How's the transfer case, and diffs fluids? Grease up all the ball joints?

Trans fluid....ever done that you know of?

Btw... banned for not searching

 

[PG01]

So your list

-Plugs
-Wires
-Air filt
-Diffs
-Transfer case
-Transmission
-Find every grease fitting and greeze it
-Your fuel filter is in the tank so thats out

Anyone else want to add?

That's a good list to start with.

headlight mods & colormatching before vital drivetrain service, ban.

That’s pretty much it, or if you have a local shop you trust have them go through it and see if there is anything they’d recommend besides that

you'll also want to closely inspect (for wear) your steering components (tie rods, end links, bushings, front wheel hubs and shocks (front & rear), flush your cooling system if that hasn't been done already. check your brake calipers for leaks. basically anything under the truck should be visually inspected, excessive grease on anything is a indicator that it's worn or getting worn. a flashlight and taking the wheels off helps to look over everything.

No idea on the tcase or diff. I do plan on doing those. After I replace the UCA all balljoints will be new.

I like it. Once I'm done with the suspension I'll move on to this list. Thanks.

Funny you mention that. I took it to the gmc dealership here they were super cool. They told me mechanically my denali was in fantastic shape and they haven't seen one that clean in a while they also told me that my air shocks were bad, and that there was a slight leak on the block above the oil filter. I never saw any oil on the drive way. They did, however, invite me into the shop to show me and sure enough there was oil on it. He said it was an easy job that I could do in my driveway. He said other than that stick to regular maintenance and I'll be happy with it for a long time

Suspension is my #1 game plan right now. I think in the near future I'll be doing UCA, inner/outer tierods, pitman arm, idlers arm and bracket, and another alignment. Then I'll move on to fluids, I'll do the diffs, tcase, coolant and brake/psteering fluid. Then I'll do transmission fluid and filter them fuel filter and clean injectors. Then plugs and wires. Hopefully I can do this all by the end of the summer.

Hopefully that will net me a much better ride and a happier healthier engine/drive train. Maybe pick up some power and mpgs

While I'm on the topic of maintenance anyone have a suggestion for P0496 I think it is? I've done fuel cap, and evap canister. I hear something about a fuel pressure sensor that's on top of the tank or something on the intake manifold

there is 2 evap solenoids, one is on the engine intake manifold (easy to change), the other is down under the truck above the spare tire and connects up with the evap canister (that you already did), I recently did all off them on my 2012 and it took maybe a couple hours and I was doing other things and being interrupted.

I think that's the most common fault code I have seen for these vehicles lol

Not sure if 05 has cabin air filter and might have an AC tune up. Didn’t see belts mentioned and little stuff like door hinges left gate and hood struts lube them

Thanks. I did the one next to the spare. Do you have a pic of the engine bay one?

I don't think it has a cabin filter. The belts look good but I'll keep an eye on them.


Thanks for all the info. I did a quick Amazon search for a lot of parts and so far I'm at $630 lol

 

[Bombsquad85]

My OCD is kicking in because all of the parts are Prime except for the idlers arm bracket....

Two things I see.
Forget that fuel filter. Your truck doesn't have one. Yours just has the pickup screen in the pump. Also, do a little search on the moog arms. There have been fitment issues with one of them I can't remember if it's the idler or pitman. Guys were using AC delco pro for that one part instead of the moog.

yours may be a different part number, but it looks just like this and sits on the top of the intake near the front
