dealership fell down again
Recently had my cls in for 65k service. (8-05)
tire rotation is part of this interval. i subsequently was changing summer tires/rims to winter tires/rims. 4 of the 5 lug nuts on the two rear rims were properly torqued the remaining lug nut (anti-theft mcgard lug was finger tight only!)
this is the 2nd year in a row this situation has happen with the same dealer. the reason i am pissed is lug nuts should be install and torqued in proper sequence to eliminate possibility of warping and/or cracking of the rim under load conditions.
A CRACKED RIM CAN LEAD to wheel failure under severe loading or pot hole shock, etc. if this happened at say 70 mph expressway speeds this type of failure could have serious consequences.
i am not trusting them again ..... for anything

[1 lug not tightend down on a 5 lug car will not do anything.]
post#2, actually you are wrong. the wheels are aluminum alloy and are subject to crack failure if improperly torqued. there are two issues here, first is the fact that the proper sequence needs to be followed to reduce stress during installation. the second is under load conditions, wheels are subjected to intense loading especially with plus size summer tires and poor roadway conditions. where any minute stress cracking will be subjected to additional stress leading to additional permenant damage and in extreme cases wheel failure.
in this case the lugs could not have been torqued in sequence and did subject my vehicle to operation in an unsafe condition.

Ok.......Let me say it another way....
I have never seen a rim crack from the lack of 1 lugnut. The cracked & broken rims I have seen have never been anywhere near the lug holes. I have ran 5 lug cars without a 5th lug nut many times, & never seen a problem.(100's of miles)
That post sounds like it came from a text book. Facts are facts yes..... but real world is real world.
I'm just saying in real world everyday driving a failure like that is about as rare as winning the lottery, don't get too worked up about it.
I would suggest to find another dealer, since that one doesn't seem to care.

Makes no difference who put them on, aluminum wheels will tend to loosen up after they have been run a bit. I always retorque my wheels 100 miles or so after they have been off and on.
