GeorgeB’s 2013 Suburban LTZ “Fin”

[George B]

if you look in the owners manual it will explain rap and state it works with the drivers door

That is how this 13 Burb works. My 03 is gone so I can’t compare. I will say I love this one so far. Drives so nice!

First package of goodies arrived today. $50 on Ebay. All work perfectly!

Very nice suburban. My wife's 09 Yukon Denali came with 22s. I purchased a set of 18” wheels and tires. Went with the falken wildpeaks. Awesome tires, esp in the snow. I'm on roads too rough for 22s here in Maine. Will be selling the 22s this spring.

I was considering the exact same swap.

Have any pics of the truck with the 18” wheels?

Not the best pics. I can get you more though.

Imo they are perfect for this truck. Ride is much improved and they sit perfect. I like my tires pushing outside the fender just a little bit. If I remember correctly the wheels are a 0 offset and are 18x9.5. so with the lower offset and wider wheels they are out further than the stock size. Tires I went with 265 instead of 275. They have not rubbed once at all either.

Got the new rear climate control in the mail today. Installed and all better. The button lights go off as expected when you open the drivers door and the display is bright and easy to read. Easy fix!

Got some snow here today so I used the auto 4 wheel to take it to church. I noticed the transfer case does a bit of whining more noticeable in town around 30 mph. Is this normal for these? I thought I better check the fluid just to be safe and found the case is a bit overfull of the red Dextron VI. Trans fluid level is good. Not sure how it could be over full And I don’t want to jump off a cliff like something is really wrong with it yet. It didn’t look like anyone had removed the plugs in some time. And there is no note about ant TCase service to date.

If the fluid was warm when you pulled the plug it would be normal for some to leak out as it expanded. As for noise, I don't remember.

Doesn’t look like they checked the front diff at inspection. Needed the impact to rattle the plug out. Whatever was in there was foamy. I floated all the foam out with some good gear lube. Going for a drive now. Will have to drop the bottom plug on that soon. Glad I checked!!!

 

[George B]

It better but still a little noisy. Will have to change it out soon.

 

[George B]

I think the noise I have is the one outlined in a TSB I read. Don’t know the number tho. It comes and goes and is related to loading the T-case on deceleration or when there is little to no load on the driveline. It is present at low speeds up to about 35 mph but not constant. It sounds like gear whine at times. And perhaps chain noise at others. When I spin the front drive shaft I can feel or here the chain splashing fluid in the case. I don’t think it is a major problem. All the fluids are clean. I suspect the 4 wheel was used very little in this truck since it lived in MO for all but 20,000 miles or its 64,000.

Interesting read in the RAP shutting down with only the drivers door. I believe on my 2006 it will shut off with any door opening after the key is taking out.....

Does anyone think this might be an issue with the front diff bearings? I see in the carfax that some carrier bearings were replaced but I am unsure which axle...

rap has always been drivers door only, if you replaced the factory radio and did not use the proper adapter module that retains rap then you loose rap and power then shuts off from any door

Perhaps that was my issue before... I had the Rosen HU... I don't really remember what the RAP did with the factory Navi.

Yes gear noise is most prominent at that speed.

 

[swathdiver]

George, when we're driving around at low speed we hear a lot of noises from underneath, either the transfer case or front differential. I always suspect the latter. It settles into a rhythmic hum around 35-40 and then gets much quieter the faster we go. Or maybe it's the auto-volume on the stereo? LOL

Mine sounds similar to the noise a bad power steering pump makes. It comes in soft at low speeds and gets louder and higher in frequency as I increase speed. Its got a good hum from 30-40 and then just turns into a whine from there up. Didn’t go much over 50 with it.

I just dropped it off at the dealership to have them take a listen. I searched online till my head hurt last night but was inconclusive. If people would finish their threads with what the resolution was the Internet would be a better place....
