Hey all, rather than have a dozen different thread that I can never find when I want to update, I've decided to have this single thread to not only ask general Burb related tech question in, but to provide updates as I have them. Thanks to all who have participated in previous threads and to those who view and continue to offer suggestions about my Burb. Basic info: '03 Suburban, nothing major, sort of. Bought it in Feb '19 for $5400, good bones, but needed some TLC. I put around $1500 into cosmetics and minor maintenance, changing fluids, new brake pads, new shocks all around, that sort of thing. Fast forward to today, she had an exhaust leak on the drivers side manifold, 3 broken studs. Mechanic changed all but one of the bolts and the gasket, the last broken bolt wasn't removable without significant effort and expense. A fellow BITOG member turned me on to an aftermarket bracket that bolts into existing holes in the head and "thumbscrews" down over the missing bolt that I will be installing as soon as it arrives. Still chasing the suspension issue we've discussed. I think I'm heading down the right track with that one, we'll see where it leads as I have time to mess with it. Had the plugs changed, 160K, have no idea if they'd ever been out, which is why I had the shop do it. I don't have the tools or expertise to deal with a snapped off plug or stripped threads. She seems to have a little more pep in her step with the new plugs, not significantly, but noticeable. Biggest change was having the AC charged. The issue when I took it in was that it periodically would blow warm air for a few minutes then cool back down and be fine. They said the system was 24 ounce low, but otherwise in good shape, it seemed better. This was several weeks ago and it has worked fine since. She went back in this week to have the aforementioned exhaust studs and spark plugs done, when she came home the AC wasn't working at all. The pressure switch went out. They said it was unrelated to the work they did, maybe it was, maybe it wasn't.They only charged me parts to fix it, so kudos to them, happy and COOL me! It's over 100* here right now and I don't go anywhere without the AC blasting! I'm also really loving the dual zone AC! I have the passenger compartment overhead vents blowing down the back of my neck! Technically, that would be 3rd zone, as the front driver and passenger have separate heat/cold controls too, again, REALLY love this feature!!! So, that's where we're at now, still trying to diagnose and fix the suspension noise. Feel free to click the link above or chime in here if you have any suggestions.
