I was just woundering what causes wheel hopping, is it the tranny giving me the sigh that it is going or something else??
help

 

Under what conditions are you wheel hopping? When your launching? Hard on the brakes? Cornering hard?

 

normally from the engine rocking hardcore bavk and forth. u can stop it or lessen it by altering your engine mounts, ad traction bars and or different tires help a lil bit. its usually on a launch or laking off in the rain usually yield bad wheel hop

 

I get wheel hop in the rain on launch while stopped over those white stop lines. Definitely worn front engine mounts.

 

how exactly does worn engine mounts cause wheel hop? :squint:

 

basically, with worn engine mounts, once power is transfered to the wheels, since the engine isnt sittin stable, the motor is shifting back and forth all while tryin to put power to the wheels, thus causing wheel hop.

i installed a set of es polyurethane motor mount inserts, goes in the rear mount, and front lower two torque mounts, end result = greatly reduce wheel hop, more positive feel for acceleration, engine stays solid. only con is at idle, the interior vibrates more then usual because it has to go somewhere. doesnt bother me at all tho, cuz im hardcore.

 

Motor mounts and bushings. Whether they be wore out or broke. The LCAs are moving around from worn bushings, same with the motor mounts. Urethane bushings/urethane motor mounts (IE stiffer durometer) and/or maybe a traction bar will help prevent that.

 

Good catch about the LCA's. Never thought of that, but yes that will factor in as well.

 

You can induce wheel hop without there being a problem. It isn't a sign of something wrong.

It's a sign of poor launching, if this is when it is happening.

What it can do is shatter your differential and break mounts. I recommend learning how to avoid it.

 

Think of it this way, your car is at rest. If you launch it like a typical drag launch, the tires are going to start moving foward without the car and move as far as the suspension bushings will allow before they bind, at this point the car will start to move and the suspension will snap back and you will get wheel hop. This vibration/shake will be transmitted to the engine where worn mounts will allow it to shake as well, worsening the problem. This causes at best a loss of traction and at worse, can induce new directional forces on the axles and drivetrain and can break something. Stiffer suspension bushings will help keep the wheels in place and stiffer motor mounts will keep the motor from moving and inducing additional vibration, but both you will pay ride and noise penalty for (I used to have to push my knee up into my EG's dash to quiet the rattle when I sat somewhere and idled like a stop light).
