When the plastic tray that holds the lifters fails a lifter can turn sideways, it makes a ticking sound very similar to a stuck lifter. If run for much time it ruins the camshaft.

Yes, I will take off the wheels here today or tomorrow and check with my finger. I've already learned not to do that while they are hot! :oops:

I will take a look at the blower motor.


The whining certinally does go away if you cycle the key. It randomly shows up. Would that be a grounding problem as a good place to start?

Yes, but I am already realizing I think that the mirrors need to be replaced. The motors in them to move the mirrors just aren't working. The fold in feature also only works on the driver side. I've seen that these gears get stripped out and I believe they probably are for the interior housing as well. I will end up just getting new mirrors.
the radio/amp could maybe be a ground, but also could be internal failure, loose solder or a component no longer up to *****. like once it gets heated up goes out of spec, etc
the mirrors can be fixed, the adjusting motor is not hard to replace and the folding motor gear takes about 30 minutes to r&r

I went with the powerstop kit from Rock Auto. I have it listed on my spreadsheet here https://docs.google.com/spreadsheets/d/1GWTJEK0uzQ7C8TjYdxdeBgpUfOwHbz_1gknCLeX2QUc/pubhtml

The break in procedure I followed was in the kit itself. It was
30 stops from 30mph, with 30 seconds in between, I performed this for the front and the rear.


not that following their instructions is incorrect, I just feel this way is better.(see attached) it just takes a long time to complete, so no one would follow thru. I think that's why everyone just recommends the short cut. I haven't had a rotor warp since I starting follow this, even cheap auto parts store ones.

as for your whine in the speaker, I have no idea why and it was an old car when whine in the speakers with aftermarket radios was common. when mine started, I'd pull the battery cables, clean them up and put it back on. whine would be gone. I have no idea if that would still work today thou. but quick easy and can't hurt to try.

Hey all,

Apologies for the late update. It's been a crazy few last couple off weeks. We recently just had a new baby that has been keeping me pretty busy.

I still have a few things to take a look at, like the blower motor and track down the weird buzzing sound from the speaks when I use the blinker.

The brakes seem to be working great now, no more vibrations.

A new issue has popped up in the last few days, seemingly after I got it aligned. I posted about that here: https://www.tahoeyukonforum.com/threads/stabilitrak-and-traction-control-lights-issues.150828/


Since my last update, I have:


- Replaced the upper control arms on both sides.
- Replaced inner tie rods
- Replaced outer tie rods
- Oil change
- Alignment
- Billet plate, @Geotrash hit it on the head, the new gasket started leaking like 300 miles after I installed it.

Update the sheet: https://docs.google.com/spreadsheet...bu72tmHjlNl6JfKaB8RhxUZqCZEiyovnIHoMO/pubhtml

As well as some pictures, from the looks of that strut.. I think this truck has a small 1.5"-2" lift?
