    Eaton TrueTrac worn out

    its very clearly described in the initial post. with the diff cover open i can see the slop in the unit. by slop i mean how much the axles will turn indepenently before the helical gears engage with each other. And its not blown. It has worked very nicely for the past 300 thousand miles. Its...

    Eaton TrueTrac worn out

    Well, I think i am one of those guys. the factory G80 exploded on me. I didnt feel like i was abusive of it, but bang it went.

    Eaton TrueTrac worn out

    I actually had a similar issue on my old suburban and went looking in the same place. But the play is distinctly in the diffferential. With the cover open you can see the axles turning before the diff center section starts moving. I have also had the issue of the panhard bar bushsing getting...

    Eaton TrueTrac worn out

    After 6 years and around 275000 hard miles, my Eaton TrueTrac seems to be wearing out. I have noticed excessive play in it. When you pull up to a stop sign, and then step on the gas to move forward there is a noticeable slop. Once the gears engage it all works smoothly, its just that initial...

    Rear spoiler backup lights

    Lets continue the old thread! Here is the solution I eventually came up with. I have a 6 button relay control panel from Auxbeam installed, and the rear facing lights are on of those buttons. Next up, i have a set of 4 small dome lights that will be mounted inside the rear hatch door panel such...

    use the OEM backup cam with a new head unit

    I have a 2011 Tahoe LT, it has the factory backup cam in the mirror, and it has Onstar (which does not work anymore) I have successfully installed an android radio head unit, it talks to the canbus and gets signals for going into reverse, for the doors opening. And it works for all the usual...

    DOD / AFM delete parts

    I sent an email request to make a few adjustments to the transmission tune, along with a set of log files. Basically I am hoping to get the shifts to not hit so hard. I love the shift points change, but especially the 2-3 shift seems to hit hard, and pause in between gears? this is when i am...

    DOD / AFM delete parts

    Fun fact: After loading the tune files from BlackBear, I could immediately see that the shift patterns made more sense. Much improved. What I did not expect was to gain 2 MPG! This is on the normal 89 octane mid grade pump gas. :D Experiementally, on Thursday afternoon I filled up with...

    DOD / AFM delete parts

    Indeed this is a whole pile of usefull information. Answered a lot of questions about rocker arms that i had not yet gotten around to asking as well. In other news, I went ahead and got the BlackBear AutoCal. Did the initial scan and datalogging to have it tuned in its current form, and to...

    DOD / AFM delete parts

    Amusingly I actually feel exactly opposite! I would rather tear down to the heads than deal with the stupid transmission removal, and its worse with the transfer case involved. Pulling off the inner fender liners allows pretty free access to the heads from each side. The Trans was rebuilt...

    See, this is why i am asking a billion questions... I didnt know that lobe separation angle had so much to do with vacuum, and that has led me down yet another rabbit hole. Leads me to this article https://www.hotrodders.com/threads/lobe-separation-and-idle-characteristics.444889/ valves...

    DOD / AFM delete parts

    Rolling back around to one of the original points. I am looking at the kit from AMS racing Link This is using the 'Truck Norris NSR' cam, and includes lifters and trays. It is a 3-bolt cam, so VVT deletion would be involved here. One common theme in other reviews, including the one that the...

    DOD / AFM delete parts

    I am leaning towards doing the whole cam swap thing, and then getting black bear involved. In theory i should be able to drive immediately after all the installs, just on the factory programming.. do the logging and send the data off to black bear and they will do the difficult part. cost...
