Jeffrey Posted February 14, 2002 Report Share Posted February 14, 2002 it happens when you spin your tires and the tires "hop" because they are trying to get traction, not a god thing either, very easy way to break a axel, or something associated with the drive wheels Quote Link to comment Share on other sites More sharing options...
Buck531 Posted February 14, 2002 Report Share Posted February 14, 2002 Ok Beast.. then why wouldn't your wheels just spin madly instead of wheel hopping? Is it lack of weight or what? I know when I went up against a Civic Si last week that he had some wheel hop and I had none (but I spun a little). Quote Link to comment Share on other sites More sharing options...
tandm Posted February 14, 2002 Author Report Share Posted February 14, 2002 Can you actually feel the back of your car hop or what? Quote Link to comment Share on other sites More sharing options...
Jeffrey Posted February 14, 2002 Report Share Posted February 14, 2002 you may feel it, but you'll hear it even more, (thump, thump, thump) it a number of things can cause it, lack of weight, alotta power, sticky tires, a bunch of things can cause it. Brian with the dyno would probably know more than me about, but it is a nasty thing for a car to have cuz like I said it will break alotta shit very fast as it is very hard on the drive wheels and supsension Quote Link to comment Share on other sites More sharing options...
SupraGlue Posted February 14, 2002 Report Share Posted February 14, 2002 Yeah, it's a very nasty feeling. It's basically the driven tires bouncing up and down off the pavement under power, which makes the whole car shudder. There are lots of causes and cures. Sometimes it's bad bushings or alignment, sometimes changing tires helps, sometimes changing springs or shock settings helps, sometimes it's a broken or loose shock mount, sometimes bad wheel bearings can cause it, sometimes it's caused by the way the suspension geometry was designed, sometimes a lightweight flywheel can make it worse on manual cars, sometimes it's actually caused by weak control arms flexing -- every car has slightly different causes and cures. Can you tell I had to do a lot of research on it? smile.gif In my experience, if a car is already prone to wheelhop, rough pavement with bad traction will make it worse. If you ever get wheelhop, you need to find a cure quickly, because it puts a lot of extra strain on driveline parts and will probably break something expensive pretty soon.

Guest BLACKBIRD99 Posted February 14, 2002 Report Share Posted February 14, 2002 <BLOCKQUOTE>quote:</font><HR>Originally posted by Michael Knight: Can you actually feel the back of your car hop or what?<HR></BLOCKQUOTE> You'll definitely feel it with the suspension and ride quality of the T/A. It's only happened to me a couple of times in the 2.5 years I've owned mine. You can improve on that by getting suspension upgrades. Lower control arms and a panhard rod help with wheel hop the most, I think. They certainly help. Quote Link to comment Share on other sites More sharing options...
Jeffrey Posted February 14, 2002 Report Share Posted February 14, 2002 yeah almost any car can have it too, hell if I AWD launch my Talon the front tires wheel hop a bit before tha back ones catch and then is stops and the car goes. my friends Saturn has one of the worst cases of wheel hop I have ever seen, and its a SC1 SOHC saturn , he's busted 3 motor mounts because of it too. wheel hops is the Satan of cars, thats all there is to it!

integranator Posted February 14, 2002 Report Share Posted February 14, 2002 Since i switched from my stock tires to Dunlop Sp sport 9000's (super sticky) i have had TONS of wheel hop off teh line. I don't know what to do to control it?? anyone know?? Quote Link to comment Share on other sites More sharing options...

Drunkendubber Posted February 14, 2002 Report Share Posted February 14, 2002 wheel hop happens all the time in stock lowpowered fwd cars. i found that motor mount inserts help alot. stiffens the motor keeps it from bouncing and also more power. it just makes up burn instead of hop. It very bad for cars dangerous to axles. Kyle G. Quote Link to comment Share on other sites More sharing options...
GRN96WS6 Posted February 14, 2002 Report Share Posted February 14, 2002 Hey Steve gimme the keys to your car I'll show ya what wheel hop is Quote Link to comment Share on other sites More sharing options...
04r1 Posted February 15, 2002 Report Share Posted February 15, 2002 I fixed my wheelhop by puttin in Energy Suspension motor mount inserts. I dont know what you rear wheel drive guys do to fix it. Quote Link to comment Share on other sites More sharing options...
Joe Posted February 15, 2002 Report Share Posted February 15, 2002 usually, wheel hop results form a suspension that is too stiff. Picture this: you give the car throttle, and the weight gets transfer to the back. This is forcing the tires to the ground. Once the "hit," and they will, if the suspension is to stiff, the springs are just going to "pull" them back off the ground. THis is wheel hop. If you have a suspension that is too soft, weight transfer will happen at the wrong time, and the tires will spin uncontrolably. A good set of lift bars (NOT slapper bars) can help the RWD wheel hop problems. During acceleration, the pinion is wanting to rotate up, causing the springs to bind, which pull the tire back up off the ground when they unwind. The Lift Bars will use the axle's twisting motion to lift up on the body and plant the tires. South Side Machine makes a good product, and sine you are buying them, might as well get the sub frame connectors! Quote Link to comment Share on other sites More sharing options...
Nitrousbird Posted February 15, 2002 Report Share Posted February 15, 2002 I never had a wheel hop problem at the strip, but I used to have one on the street on certain bad pavement conditions. A Panhard rod won't do anything for wheel hop (it just basically keeps the rear centered). What eliminated mine (which normally wasn't too bad) was new lower control arms and my Spohn solid mount adjustable torque arm. That probably made the most difference.

Guest bird of a different motor Posted February 15, 2002 Report Share Posted February 15, 2002 ok honestly i will answer this, but.....i have NEVER seen so many f*cked up answers for what "wheel hop is and what causes it". Wheel hop happens as result of torque and the twisting effects on the rear gears,and axle in your case mikey knight. here is what happens with "rear" wheel drive cars. as you apply power to the drive line and you do it very quickly, it will cause the pinion angle to raise. In normal terms the front of your pumpkin will try to raise up. This force that tries to rotate the rear axle is counter acted by the suspension, whether it be control arms or in my case, leaf springs. now,...the twisting force and subsequent rotation will stress and move up in the suspension then it will snap axle back into normal position when your tire loses its traction. your wheel will plant and it will happen again until it repeats the process. Now many of your guy's fixes do work. but the easiest way to fix it on a rear wheel drive car is to "preload" the pinion angle down ever so slightly so that when this torque and twisting tries to happen it only pushes the pinion angle to normal. So again, in normal terms, preset the front of your pumpkin down so it will only raise till the straight setting. Traction bars, like slapper bars, use the fact that this twisting will happen so that they will work. If anyone wants a better explanation, i will show you what can happen and how i have set my car up to prevent it. as for front wheel stuff.....No f ing clue. but that is what happens in "wheel hop" wow that was like a mark or renner post.

Scotty2Hotty Posted February 15, 2002 Report Share Posted February 15, 2002 Got a problem on your bird Steve? Hotchkis makes control arms and a full rear suspension for it if you need to control your wheel hoppin. Quote Link to comment Share on other sites More sharing options...
Guest Nbodyraser Posted February 17, 2002 Report Share Posted February 17, 2002 my buddy devon stopped the wheel hop in his ranger real easy.....he just stopped touchin his sswitches smile.giftongue.gif Quote Link to comment Share on other sites More sharing options...
Guest jimmy Posted February 18, 2002 Report Share Posted February 18, 2002 One of the causes of wheel hop is worn down tires. I used to have wheel hop on 1 of my mustangs, and when I put new tires out back, the wheel hop went away. Quote Link to comment Share on other sites More sharing options...

Lustalbert Posted February 21, 2002 Report Share Posted February 21, 2002 really wana clear up the weirht tranfer and hopping issues, try a custom 4 link, and move your axle as far forward as you can. the further forward it is, the more wight that will be transfered when you launch Quote Link to comment Share on other sites More sharing options...
