Rear wheel hop
 

Hey all.

I recently installed a quaife diff, and whileline diff bushings.

This morning when I was leaving for work, I decided to lay a strip when I was pulling out of the driveway. I got some pretty intense wheel hop. It was about 60 degrees out and obviously the tires were not warm yet. Did that have something to do with it? Only other mods I have in that department are swift springs and 11 inch re11's in the rear.

Hopefully I didn't install something wrong...


Thoughts?

And I wasn't laying a strip to be a jerk, just wanted to test the new diff ;-)

odd... people swap that rear diff bushing to prevent wheel hop, no?

and punching a cold engine and tranny and diff? :ugh:

Engine was idle for a bit. Tranny is bullet proof. Knock on wood....

That's what I thought, but it was pretty bad...I'll do another test with warm tires...

I'm wondering if I tightened the bushings enough, I did it until I could see the bushings squish, breaker bar tight, but not maxed out with the metal spacer/guide

you should torque the bolts to specs. the two long bolts are 74 ft lbs and the one nut in the back is 81 ft lbs. i have quaife diff and energy suspension diff bushings. launches like a mo fo! no wheel hop.

I'll get back under there and torque them better. I'm assuming it's somewhat close, I had the handle off my jack using that as a breaker bar

If the above doesn't work upgrade your rear suspension bushings (camber and traction arms) or even better upgrade them completely. When u launch, your suspension geometry changes, upgrading some of this will help

if you're working on a car, you need a proper torque wrench. this is the one i use:

it's a snap on brand.

I have a torque wrench :-) I just wasn't sure what the torque specs were. Couldn't find it for the life of me.

I also have spc camber kit I forgot to mention

Cold tires were definitely not helping...

And I hope the engine wasn't cold if you were revving high RPMs...

There is some good info on wheel hop (have to sort through some garbage though) in a variety of threads on the forum, so you might want to do some reading as well. All I can say is I get wheel hop when I give the car too much throttle too early on launch. I control it by managing my throttle input better. I would hope with your recent mods that warm tires will virtually eliminate this, but if not, try backing off the throttle a hair when the wheel hop occurs.

Interesting as i just put in my SPL bushings in this past weekend and i also have a quaife diff too. On my test drive i laid down two 100' strips with no wheel hop at all.

the little metal spacers are the stops that set the bolt height, properly torqued everything should be nice and tight, make sure you are using the correct combination of washers at the front points for the white lines and that they are installed in the correct direction. Improperly tightened bushing will for sure give you worse wheel hop than factory bushings. but check over the other bushings back there make sure nothing else looks exploded or torn/worn out.

wat tires are you running? im sure tires are a big factor too...

not that i suffer wheel hop, with all this talk about that one rear diff mount bushing issues, i actually went under my Z and G last night to check on the rear bushing. wheew...no leaks. lol

Let me tell you, that ish is nasty... when I was drilling a hole through it it exploded and it looked like I killed an alien
