Hey, if you don't want to re-torque the lug nuts, whatever floats your boat. It's your life. I'm just trying to share my professional experiences with this topic in the hope of helping you and others out.
Me, after all the times over 30 years in the automotive industry I have personally witnessed lug nuts coming loose with aluminum wheels that haven't been re-torqued, I'm not ever going to take the chance. I personally almost had an aluminum wheel come off my own car that an auto center claimed the lug nuts had been re-torqued, but they didn't. If I had been the typical driver that doesn't know much about cars and didn't pull over to investigate a loose steering situation and discovered a wheel that was about to come off, I might have been seriously hurt or even killed.
The Ford Focus 2.0 Split Port engine, (in my humble opinion), is a complete piece of junk! I've read of these ticking time bombs grenading in as little as 60,000 miles. The engine is notorious for dropping valve seats and destroying the engine. An owner of such a car can't even drive out of town without fear of their Ford engine failing on them!
I used to have one of these cars and after putting $1,000 into the car to correct other known problems with it, (like the defective ignition locks that fail and leave you stranded that only costs $325 to repair!), the engine had the catastrophic valve seat failure! A used replacement engine from my local junkyard with 77,000 miles on it is a whopping $1,700! They can go fly a kite!
This engine had this problem going all the way back to the Ford Escort. Ford knew about it, did nothing to correct it and installed the engine in the replacement for the Escort, the Focus! Oh yeah, most of them don't fail for 100,000 miles, which is just long enough to get out of the warranty period and screw over some unsuspecting motorist who buys one of these pieces of junk!
It will be a cold day in hell before I own another Ford, ever!
