What's on your mind?
How's it goin'. I've got a bit of a pickle here. My Jimmy has been making a rather loud bang whenever I have the misfortune of being forced to tackle a decent-sized pothole or moving up the angle of a driveway, pretty much any movement other than normal driving/turning. The noise is coming from the front end, seems like it's under our feet. Now I'm not entirely a car expert, mostly general automotive knowledge, the kind of 5-minute diagnosis knowledge, (I work at Autozone). I THINK it's the torsion bar, but not quite sure. Any thoughts?

It's going to be your Torsion Bar Insulator that will need to be replaced. There are two of them on ether side of your Jimmy, the drivers side is easy to replace but the passenger side is harder to replace.
With stock exhaust, You can't jack up the cross member high enough. As for unloading the torsion bars, here's what you need to do. Jack up the opposite side from the Jimmy from the one you're changing.
If you have access to a cut-off tool, here's the trick for installing the passenger side, once you destroy the old one getting it out. Cut about 3/8" off the stud. It'll fit in with the clearance you've got. I hear if you can find MOOGs, they actually have two part numbers, a left & right. The Moog's has the shorter stud by design. The TRW's didn't. So out with the air tool to cut down the studs.
Good luck and will take about 1.5 hours to 2 hours, from start to finish depending on your level of tool use.

Much appreciated, I'm going to see about ordering the parts and finding a free day, a buddy for the tools I don't have and a case of beer for said buddy. 
Should be an intersting afternoon, I expect some swearing. Thanks for the info Molson. -Nod- I'll see about posting an update after I tackle the truck.

Hello, hive! I have a 1999 GMC K1500 Suburban. When I step on the brake pedal, no keys in switch, the dash and marker lights come on. When headlights are off, driving normally, both turn signals work normally, but the dash and marker lights flash with right turn signal. When headlights are on, left signaL works normally, but right signal buzzes a little at the relay, but does not blink, even though the rear lamp does light on the right side. I am at a loss. So is my mechanic. Help??

I'm replacing a lower seat foam and leather. The lower foam is attached to a smaller metal frame and is then bolted to the main seat frame. At the rear of the foam/smaller frame there are 2 locating pins that must fit into holes at the rear of the lower seat before the 2 front screws line up with the holes to put screws in. I' not sure what to call them but I need at least 1, 2 would be better, help please.

"I've come across quite a few articles about lifter damage lately. I assume much of it is marketing hype, but I suspect there’s some truth to it in certain cases. Any thoughts or real-world experiences?"
