<VV> Brake drum balancing

Tue May 19 05:05:53 EDT 2020

You don't need an on-car balancer, although that would be nice - just 
jack each wheel up in turn and spin it. Run it in gear at idle to check 
the rears. One of my rears is out of true, but I haven't yet established 
whether it's the (wire) wheel, the adaptor or the hub. Get it 1/4" off 
the ground and watch the gap underneath the wheel. Best chock the front 
wheels in case it falls off the jack!
