250 ft lb is way too much torque on spherical collar screws holding on steel or alloy road wheels.
My Daimler Benz Passenger Car Technical Data book says tighten them to 110 NM, equal roughly to 81 ft lb if I didn't botch the conversion. No wonder they are hard to get off when torqued to 250 ft lb. The wonder is that they survive being so overtightened without damage to screw, wheel, or hub.

I should know this by now!) All fixed now and it allowed me to give the inside of the wheel a good detailing too. Just have to do the other three now.

With the last one of these I had, the lip on the inside of the wheel was damaged. Adding anti-seize is just working around the issue.

Wow. How could anti sieze hurt? Use it. I use it on just about everything unless the manufacturer specifies a sealer or adhesive on the bolt or joint. Anti sieze is one of the great inventions of the age of old cars. Don't put it on too thick, or it will run radially and could wind up splattered on the brake dust inside the rim. And the problem then would be ? Sun, 19 Aug 2007 13:25:08 -0400 Subject: [MBZ] Stuck wheel!!!!! "E M" < [EMAIL PROTECTED], wrote Took one of the wheels on the front of the W124 the other day. The guy in shop had it on SO tight, I had to use a pipe on the wrench to get the bolts off!!! Once the bolts were off, the wheel was stuck to the hub. AH! After finally getting it off, but driving it, using the brakes hard and allowing it to heat sink a little, oh yeah, plus some pounding on the tires with a hammer against a piece of wood, it came off. There was some light rust on the hub. I cleaned it off with steelwoo, and also the big of rust that was on the aluminum rim. No, the rim didn't rust, hee hee, but the rim was on so tight, the rust from the hub was imbedded in the rim!! So, the question, I know we recently had a chat about anti-stick paste on lug bolts, but what are the thoughts about some on the back of the rim, where it meets the hub, or more accuratly, I guess it's the face of the rotor? I do this with other cars with steel rims, but haven't do some in the past with aluminum rims. Any thoughts?
