I think an anti-roll bar connects two wheels with a spring which is pivoted against the chassis, with the intent to minimize their relative-to-the-chassis differential motion. Track rods are relatively primitive linkages to keep live axles in the same county as the rest of the car. We've all seen them, but they're so obvious they're easy to ignore.

I think an anti-roll bar connects two wheels with a spring which is pivoted against the chassis, with the intent to minimize their relative-to-the-chassis differential motion. Actually, it minimizes the independent up-and-down action of the wheels at that end of the vehicle. In order for the vehicle to roll, one side has to go up, and the other side has to go down. This bar minimizes this by resisting indepenent motion in the up-and-down direction. Track rods are relatively primitive linkages to keep live axles in the same county as the rest of the car. They accomplish that, but this is not their main purpose. We've all seen them, but they're so obvious they're easy to ignore. Through a non-obvious set of kinematics, track rods are used to control the roll center at that end of the car. The roll center is the middle of the track bar, so the location of the exact attachement points is critical. BTW, right after grad school I spent about 3 years in Chrysler's advanced chassis analysis department. Then the company almost completely folded., hopefully no fault of mine! ;-) |

Gaffer tape and duct tape are not synonymous. Gaffer tape is muc easier to work with for the jobs us audio folks have seen duct tape used for such as taping down cables etc. NO sticky gummy residue left behind for one thing. It is alleged that we have residue-free duct tape in the US. HOwever, leaving a joint duct taped for three weeks which is that important to the safety of your vehicle is irresponsible to say the least. THis fool ought to lose driving priveleges just because he's an idiot. Agreed. MOre like a menace to others. Well yes, if a suspension joint separates, the car goes out of control. More would be killed were ball joint sepration not so much more common at very low speeds. |

Well then, here's another use for "The Tape".
Duct tape for embalming! "Slap 'em, Wrap'em and say good-bye" Tom "Robert Morein" wrote in message ... "Mike Rivers" wrote in message news:znr1094299860k@trad... I was listening to NPR's Car Talk program while reading the newsgroup messages this morning. A caller had a ball joint break when he was driving, and he didn't want to pay for a tow, so he put the pieces back in position, wrapped it in duct tape (he had a roll in the trunk because it was an old car and he'd need the duct tape for something, sometime) and drove it home. He said he'd been driving it that way for about three weeks. That's an invitation to an early death. Loss of a wheel, which this is very close to, has been shown to inevitably result in complete loss of control of the vehicle and a serious accident. |

I agree, how stupid can one be. Driving for 3 weeks with a major component taped together? I was once given a beat up loaner car to use while my car was in a repair shop. Not 5 minutes into my drive one of the front wheels came off! Well, I was going less than 30 mph but it was still a very frightening (and jarring) experience. Had I been traveling down a highway at higher speeds, I can only imagine the outcome. Been there done that. My wife and I were heading back for Iowa after taking her youngest daughter and family back to the Memphis Tn area. On highway 61 about canton Mo. we stopped at a rest area to get a couple of hours of sleep then headed on. I was asleep on the back seat of our van. WE had a front tire on the right side that we were sure was going to go about any time. I awoke to find us crashing down the road, thinking that when that tire blew the wheel split and we were really in deep doo doo. COme to find out when we brought it to a stop safely on the side of the road that the wheel had come off. Btw the tire was still good. What saved us was the fact that the wife didn't touch the brakes. Had she I'm sure we would have flipped over. The fun part was getting the now disabled vehicle out of there. WE were on a blind curve on a hill. I don't carry a cell phone, but had my trusty vhf ham rig. A local ham radio repeater had all sorts of bells and whistles so I figured it had automatic 911 interconnect if I just punched those digits. I was right and was soon connected with a 911 operator in Adams COunty Illinois. AFter she figured out what was going on and got straight on all that she relayed my information to MIssouri state patrol who sent us a tow truck.
