i noticed today i had a flat tire, so i went to take the wheel off to patch the tire. and i got the first 4 lugs off but the fifth wouldnt come off. it just spins freely, i had to apply pressure as i backed out the bolt.

i am assuming that this is my wheel hub that is stripped? i had the tires put on when the car was inspected i guess it is too late to go back and blame it on the tech. any ideas for a quick fix so i dont have to buy a new hub?
btw this is on my 81 300d.

I did this too years ago. But on an 88 Mustang.
Just guessing here, and I would think there are similar ways to fix the problem on a Mercedes. I used a ballpeen hammer and pounded the bad stud off the hub.
Then got a new stud with nut from Napa auto parts.
Poked the new stud back through the hole left by removing the old one, and put the nut on wrenching it down to "draw" the new stud into place.

run a tap in to clean the threads, then run a new bolt in the hole and see if it will hold torque, if not then yes you will need a new hub, or a PNP hub

If the threads won't clean up with a tap use a heli-coil.The finished job will actually be stronger than the original thread! We used to install them regularly on aluminum race heads to keep rocker studs from pulling out of the aluminum bosses.

Problem is i dont think there is enough metal to even hold a heli-coil.

Then tack weld a nut to the back side of the flange. Not enough mass & too close to the axis to effect balance.

Mercedes makes available a "Special" tap for this very purpose
(I'm sure a tap of the correct Twist and diameter will work[AND be much less] )

Since when does Mercedes offer anything "special" for less than commonplace hardware?

If it's a Front Hub, a used one should be easy to locate.....and change out.

A Rear Hub poses greater problems.....

The threaded area is about 1/2" thick so you should be able to heli coil it.

..I also have a 427 Cobra replica with an aluminum chassis.

I would heli coil it. If you chose not to then get a used hub at a junk dealer and install it.
You will need to redo the bearings.
