My 1997 Ford Expedition has a mod. vibration in the front-end only in drive at a speed of 35-40mph and violent vibration over 50mph.\nI had the wheels and tires balanced and rotated with no change. Had a front end alignment with no change.

I agree with the last answer. You have a bad tire. Balancing a tire will not identify an out-of-round tire necessarily. You probably have a ply or belt separation in one of your tires. It's visible by a bobbing rather than smooth rotation when it's on the balancing machine. The problem is that balancing machines have a safety cover to keep the technician from observing the perimeter of the tire as it rotates on the machine.

You can't just ask for an acceleration.  You need more factors.  All you know is that it went East 3000m and North 6000m.

just loosen or tighten ur trucks

i had the same problem with my 91 lumina with a 3.1 multiport, one of the cylinders wasnt firing properly, so at about 45 mph she would really start shakin so i just drove around with it in a lower gear. might wanna check plugs,wires, power pack, and air filter, maybe even spray out throttle body.. if u have a schrader valve check fuel pressure while at it. could be exhaust related too if the cat is clogged.  just some ideas

Happened to a couple of my cars. Take yours to a transmission shop. There's no quick fix.

Damn, I did the same thing to mine last weekend! Lucky for me, I just pushed it back into the water after running up on an unseen sand bar - and it started right back up, no problems.  I dunno about yours though -- I guess it would really depend on how much debris you sucked up in the intake. I think all I had was a little bit of sand, no rocks. Gotta be careful not to damage the turbines. If it's bad, I'd probably call Yamaha and get them to tell me what they thought. Good luck.

The harmonic balancing of rotating shafts and machinery including wheels and turbines. Without this process, out of balance forces would tear the machines apart and cause very severe vibration. The diesel is a lot beefier compared to a similar cubic capacity petrol engine. The diesel will usually be fitted with an injection pump and injector pipes a petrol engine isn't. Jules. Australia.

hey dirt. never mind what Piston Fan99 says. that was a good question. i don't know the answer to it but it was good question.

my dad has three dirt modifieds and is selling 1 and racing 2 if you want a chassis talk to my dad he is like famous he won thew super nationals in iowa one year. he has parts for dirt mods and can maybe build you one because he built some mods before if u want the phone # talk to me on yahoo at hobbystock55p. thats all i have to say and if you need more information talk to me on yahoo.

adjust the trim tab, check the prop, and check for a broken steering cable or part. More than likely you trim tab is out of adjustment. good luck

it depends on how good the engine is...generally the higher ps will consume more...but you cant use it as a rule of thumb

On a stretch of road that ran straight for about 3.5 miles, I clocked a oncoming vehicle at 136mph. I had never had one that high and was wondering if the radar was not accurate. I reset it and it showed 147mph, to my luck another unit was behind me about 1.5 miles and was able too stop the vehicle. Needless to say no ticket issued, he was jail bound and his vehicle towed. Not had one that high since.

Torque is less of an issue when racing because you are always running the engine at high revs. I raced stock Fords here in England and the revs were always between 4500 and 7000, even 4500 was quite unusual.\n\ni would normally take power to weight over torque to weight any day.  Weight works against any race car as it strains everything, tyres, brakes, etc.\n\nAlmost certainly in a race there would be other deciding issues such as set up (camber, toeing, etc)

The motion was caused by the human reaction to small lateral movements in the bridge, which set up a driven harmonic motion in the bridge. As such the motion was not anticipated by the computational analysis of the bridge prior to construction. It is often thought that the unusually low profile of the suspension cables contributed to the problem, but an analysis by the structural engineer, Arup, shows that it can occur in any suspension bridge which happens to have the appropriate resonant frequencies. After extensive analysis, the problem was fixed by the retrofitting of 37 fluid-viscous dampers (energy dissipating) to control horizontal movement and 52 tuned mass dampers (inertial) to control vertical movement. This took from May 2001 to January 2002 and cost £5m. After a period of testing the bridge was successfully re-opened on 22 February 2002, and as yet there have not been any noticeable severe vibrations.

Why wouldn't you make an Tempo into a race car?...It's the perfect sleeper, and like it or not, I've seen quite a few made to race...\n\nDid you change the Onboard Diagnostic System?...Because it should be OBD-I...

Ok assuming you are part of the real world and race on the street where they dont have a tree, sorry race chick. There are several things you can do to improve launch i have had a 89 mustang gt and i didnt do alot to the engine at first it was all about suspension and other things to get me off the line faster the first thing i done was put in a trunk mount battery kit to help waight transfer then 40/60 drag shocks fron edlebrock and eiback 1" lowering springs in the rear also i ran a pair of Nitto drag Radials and 3.73:1 rear gears you can email me @ williamb606@yahoo for specifics

Probably for the same reason there are lowriders and chopped motorcycles...cuz they can. In my day it was cubic inches and horsepower. For the life of me, I can't figure out why someone would spend thousands of dollars to make a car jump around like the devil is behind the wheel. But I do admire the hard work and innovation that goes into making it happen. Don't ask why, admire the work and move on if it isn't for you. C'mon...some of them are actually pretty cool :).
