Annoying Sound

bigman32hockey · October 12, 2019

Well, I have yet another gripe with my 2018 Silverado 1500 (6.2L/8-Speed). I experienced this same problem with my 2017 Silverado 1500 (5.3L/8-Speed) but it didn't seem to be as noticeable. When I'm cruising along at a steady pace, say around 40, and apply light throttle, I get this noise coming from the drivers side of the truck that sounds like a leaking exhaust or something. It's like a ticking sound that drives me up the wall. I swear this truck is the biggest POS I've ever owned. It doesn't matter if I'm in regular drive, Tow/Haul mode, M7, etc.. Since this happened on my 2017 as well, while not as pronounced, I was wondering if someone can lend some insight into what is causing it. Is there any way to get rid of it? Thanks in advance.

There are soooooo many threads on this. Remove steering shaft boot and repack with grease is a common fix, as is Dynomat where it comes through the floor.

Google PIP5570 it’s a bulletin on the problem. Don’t stress man

I brought the truck to the Dealer to have this fixed. They said they followed the procedure in PIP5570 but the sound is still there. Not really any better than before. I made another appointment to have them look at it again. I'm probably going to have to do it myself. Any tips on removing the steering shaft boot and packing with grease?

This noise happened everyday, all the time. I brought this to the dealer, to no avail - it’s a 2018 Yukon Denali 6.2 with 2k miles and has done since 22 miles on the odometer

My seal appeared to be fully seated as well, however there was some play in the seal on the steering shaft. I ended up purchasing a new boot (p/n 25815601) and white lithium grease from Amazon ($35 total). I removed the 15mm bolt from the steering shaft, and removed the 3x 10mm nuts from the boot on the firewall, and removed.

Looking at the old boot, it is different - looks like a different mold on the multi-layer rubber. I also noticed a fold on the rubber where it meets the firewall.

I took the new boot and packed it with white lithium grease, perhaps not necessary, but this noise is extremely annoying. I installed the new boot, catching all the extra grease that was pushed out. Made sure it was absolutely flat against the firewall (it was getting caught on the insulation - had to move it around to seat properly). Installed nuts, torquing down until the seal was pushing firmly on the firewall, and installed the 15mm bold in the steering shaft.

No Noise!! It’s completely gone!! Worth every penny and the 30 min to change out.
