I have owned 3 Chevy Tahoes, one 2 door, and 2 4 doors. Every one of my Tahoes has been lifted and modified in someway, shape, or form.
My latest 1999 Tahoe, a four door of course, has now had 3 motors put into it, about 5 4l60e transmissions put into it, 3 transfer cases put into it, 3 rear axles put into it, and two front diff, not including all the high performance suspension parts put on, or the lift kit put on.
I've change the alternator about 17 times, and the power steering pump just as many times.
I've replaced the water pump 3 times, and all of the front engine accessories.
Had numerous distributors and ignition related problems.
Had to replace the drive shaft about 15 times.
Right after I got done with all that work, which was in about a 4 month timespan, the cads went out and the O2 sensors, and then the pass-lock sensor, and then the ECU.
I've replaced the whole interior, and just about everything on the exterior, and stuff just keeps breaking, no matter what I do, but the best part of it is now that I've replaced everything, it's now all under warranty, so it's free to fix, and all it takes is a little bit of labor.
I've done all the fixing myself, and I absolutely love this Tahoe. Yeah it's a lemon, and it breaks all the time and costs a lot, but I've put the truck through hell and back, including driving through a pond.
