2 Post lift and expansion bolts

[GMCAMARO]

So, I have a two post lift and the expansion bolts which I was told to test once a month are getting near the top of their travel. Should, I drill out those that are nearest the top of their travel limits and replace them with epoxy ones.
I was thinking of these and wondered if anyone had experience with this company or these bolts?
Just looking for help, thanks.

The answer hasn't changed since the last time you asked it: STOP re-torquing the bolts. The person who told you to do this is an idiot. You are causing your own problems.

Once torqued, if you have the proper fasteners for your lift, you MIGHT re-check it ONCE. If you're really **** check it again after a year of use, at that point, if it hasn't moved, it AIN'T GONNA.

Now not knowing what your installer USED, I can't comment on weather you have the "proper" fasteners, but most lift manufacturers will have published specifications for the fasteners or epoxy systems used to install, make sure you have something that meets all of those specifications.

I re-asked the question because, I am concerned and money has become tight. My installer used 1" expansion bolts. Also, when I check them I find they do not meet the torque settings specified by the manufacturer.

Ah, now we understand they are failing the OEM specs, that's a little different story. If they do not meet the torque specification as specified by the manufacturer, then you have three choices:
1) Replace them regardless of money, in favor of your personal safety.
2) Don't use the lift.
3) Continue to use the lift with the full knowledge that it is an un-safe installation, until such time it falls, endangering your life, vehicle, and property.

Now having said that, why not just find an epoxy system that meets the manufacturer spec (Hilti and redhead are the two I would consider) and get the fasteners done correctly? In the long run the cost of new fasteners and epoxy are minimal compared to repair/medical/lost wages if you were to die under the lift.

Last but certainly not least, once you have the new anchors in and set the torque appropriately: LEAVE THEM ALONE.

Did they meet the torque specs when they were first installed? If so they should have been left alone. I have installed thousands of Hilti brand expansion bolts in industrial applications. In industrial applications you torque them, QC inspects them, puts a dab of loctite on the threads to show they have been inspected and then you leave them alone forever. If you go back and tighten them once a month like you said you were told to do they are guaranteed to fail.

My two post install instructions say to set the expansion bolts at 150ft lbs. (Mine are 3/4" bolts). Then backoff and tighten to 80ft lbs . Then to check monthly to keep torque at 80ft lbs. I'm sure that the monthly check requirements are meant for the lift when used in a business shop environment where the lift is run up and down multiple time a day. I've had my lift for two years (home use) and have checked the torque maybe three times since the install and the torque has stayed at 80ft lbs. I put up cars on my lift around two to three times a month.

I installed my two post lift today. It said to torque to 85 lbs. and to check periodically at 50 lbs.
