if you have a High Lift jack you can use the handle for leverage on the end of a socket wrench. that's what i typically do if i don't have access to an imapct
Ditto, anything you can slip on the end for leverage will work - pipe, bicycle hand bars, even thick pvc...
Worst case, if still looking for tools and feel like driving to Lewisville, I'll help ya out.
BTW, if you haven't already, invest i na can of PB blaster and pre-soak 'em first. It works wonders.
Go to northern tool and buy an electric impact...it will make your life much less miserable. Otherwise, I've got one here in morganton and I'll be home for a week.
