Wheel hopping, Excessive front left wheel hopping Options

[yozef]

I have been experiencing excessive left front wheel hopping on hard launches in first gear during the past months.

On another forum somone had suggested to check the shock as it may be dead, others have suggested a check the engine mountings.

Since then I have replaced the shocks with Koni adjustables and found out the fron engine mounting was dead so I replaced that as well.

However this did not help a lot and I am still heaving excessive wheel hopping on 1st gear hard launching.

Has anyone experienced this before, I do not think this is normal as I had never had such a problem before.

I only wheel hop in the high range at 3,000 rpm and half throttle I never wheel hop and do a nice burnout, at 5,000 and WOT I almost knock my fillings out. I can make a video of it this weekend if you want, if I can get a camera with sound. The same thing happend in my Sierra when I would go 4,000 or higher I would wheel hop, but when I was finishing a burnout I would just shift into third and that auto gear range slowed my wheels and I would wheel hop.

BTW I know what you're talking about and that is wheel hop but it's the wheel catching traction due to very slow wheel spin not high torque forcing your wheel to jump a lot of cars with stock tires do it, if you can get a manual GT tach it up to 5,000 and dump the clutch you'll see what i'm talking about.

For the question have you changed tires recently? Does the steering wheel pull to the left when you launch and how high of an rpm do you launch? Power makes a difference, my 5S doesn't put the power out a 3SGE does but im about 15-20 lbs. ft. less so it would be similar, try lowering your launch rpm to 4,000 and see if that makes a difference, also a bent wheel could be a factor.
