Ticking/fluttering sound from driver's footwell - TSB #PIP5570

Just to report in, I filled our boot with grease yesterday and the noise is definitely gone.  2019 GMC Yukon XL Denali, 44k miles.

I ended up swapping mine out on Saturday as the “grease trick” was starting to wear off.  Three 10mm nuts on the firewall and one 15mm bolt on the shaft.  Push up to compress the shaft and disengage from the lower portion and slide the boot off by pushing the shaft (rotates freely) towards the engine (so the boot clears the brake booster) and reverse for the new one.  I packed the new one with GM superlube grease that it plastic and rubber safe.

 

I could have gone to the dealer and gotten covered under warranty but get satisfaction out of fixing things myself.....

Did your truck stopped doing this noise either turning to ur right or left?

then drive straight again and it came back?

2018 Silverado flutter noise

 

I had GM replace the boot to the firewall and it’s still making this noise  

any other ideas?

Just a quick note, I have a 2016 Tahoe, the flutter/ticking sound has been annoying us for the past 50k miles. We followed the procedure as outlined and the noise is GONE! Thank you! We were thinking of getting a new rig...not anymore!

Do you replace the boot or just pack the grease?

Hope this works!!  I just ordered the boot and grease.   This has been driving me nuts all summer.   Dealership inspected the seal beginning of the year but didn't replace it so it wasn't fixed.  Driving with the windows down or with the music loud is not a good fix. 

DO you have the part number?
