5.3l 4wd tahoe. Great part but incredibly difficult to install because of the lack of clearance. The following is what finally worked for me after hours of frustration. Be prepared to walk away and find your calm place several times. You are trying to thread 2 bolts that you can barely touch with your fingers tips into 2 holes you can't see in a place with no room for a socket or a wrench. Expect frequently dropped bolts and parts. You will have to work from the top and bottom and go back and forth many times. Best advice came from ernies review. Dropping the front driveshaft on a 4wd was best tip of all. Heres what I wound up doing. Jack up tahoe just enough my gut can fit underneath. Remove 4 11mm on front of drive shaft. Slide driveshaft back and let it hang. You don't need to remove it. I needed some wd40 and a prybar to break it loose from rust up front. You can now see the two bolt holes on the head that you can only feel from the top. Remove the heat shield! It's a pain and you'll only gain maybe a 1/4 inch of clearance but you'll need every bit of it. 3 10mm nuts hold the heat shield on. Two you can see and reach from the bottom. The third is hidden behind the steering column and you'll need to get it from up top. Now the hardest thing for me was trying to hold the part in place while trying to fish blindly for the bolt holes. The weight of the part makes it want to fall just when you think you are about to tread the bolt. To solve this I used smaller bolts as pegs to pin the bracket into the bolt holes. The 11mm ones from the driveshaft worked great. I used a magnetic pick up tool to hold the bracket in place while I pegged it with the smaller bolts. This way it was in place and the weight was supported so all I had to do was work one bolt at a time. I went up top and found I now had just enough clearance to get a thumb and finger on the top bolt. I took the peg bolt and threaded in the top bolt. I finger tightened it and went back underneath. With the bracket held in place it was much easier to start the lower bolt. I wound up using a 14mm socket, a wobble and about 18"s of 3/8 extensions to thread it in. You can do it with a wrench but expect to move it a 1/16th turn at a time. I snugged up both bolts with a wrench once they were all the way in. There is no clearance for a torque wrench and it's not needed anyway. These bolts are side loaded and firmly seated is enough. It was now easy to go up top and install the clamping bolt with tread locker. I hope something in this helps you. It's a good part and a great solution. I know how to pull the heads and the broken bolts. This was just as good. Best part is you can walk away at any point and still have a driveable vehicle. When pulling heads you are likely to break or snap something. If you don't have another vehicle you are then stranded. Good luck, take your time and trust me it will work....eventually :-)
