My daughter is driving a 2002 Outback (277k), and lives in a small Colorado mountain town with dirt roads. On a trip to Denver in July they noticed noise and thumping, and discovered 2 lug nuts gone from one wheel, and a couple loose on another wheel. Today she called because on one rear wheel she found loose lug nuts twice in 3 days - 2 to 3 lug nuts each time. It is obviously dangerous.
First question - anybody run into this before? This is our 6th Subaru (I bought it before our daughter got it) and I have not seen this as a recurring problem.
Second question - what is the proper way to tighten the lug nuts? She has a T shaped lug wrench, but not a torque wrench.
Can the car be sitting full weight on the ground while tightening ? When working on cars, I usually tighten them with just enough weight on the tire to keep it from spinning around (using a jack or hoist).
It is possible some vandal is doing this, but that is unlikely for a small town school teacher -- but you never know.
Thanks people, look forward to your ideas.
