Changing Harmonic Balancer on Quick Jacks
I have a question about changing the harmonic balancer while up on quick jacks. The QJ seem really stable but when you need to torque the HB will it be stable enough? Anyone done the HB change while up on QJ? Thanks for any comments. Bob

Not only have I done it before I've done it three times before.
If you are worried about it lower the car back down so the wheels are touching the ground and then torque from the top.
I prefer to torque from the top anyways so there is more swinging room. I personally skip the torque wrench and just use a 36" breaker bar and pull until I can't pull anymore.

I did it on two walmart 10$ jackstand under the front. Undid the rack, tie rods,abs bracket, block and the rack slide out the passenger side halfway enough to change the balancer, cam swap not too bad maybe 2-4 hours changing a balancer or front seal whatever youre in there doing.

Just use an air, or strong electric impact to remove. I've used an air impact to R&R my balancer for almost 20 years, off and on 3 or 4 times for different cams. Never came loose. Don't use an impact on the stock bolt for tightening!! Use an impact to tighten only on an ARP bolt. My .02.

Yes, stock bolt is torque to angle, and can't be reused. For all the torquing and angle measuring hassle the stock bolt needs, just get an ARP bolt, and use an impact. I guarantee a shop will use an impact to remove the old stock bolt. If you ever need to 'go back in there,' the ARP will pay for itself the first time this happens. My .02....

I did mine on Quick Jacks, it was no problem at all. Very solid. However, just due to the height, when it came time for torquing the ARP bolt, I set it down to almost touching the floor.
