Put my W140 into kiwk fit today for an MOT - passed no problem :bannana:
Thought I'd get the four wheels balanced while it was in there for 20 quid. When I went to collect it, they said they couldnt get the wheels off - the bolts were too tight and they were frightened of snapping them and leaving the car inoperable for tonight....
They said you have to be careful and tighten the bolts only with a torque wrench, to make sure you dont overtighten them. Funny that, kiwk fit put the wheels on last time and I seem to remember them using only the airgun - maybe my memory is faulty. I asked what torque they put the bolts to and they claimed 110Nm. My manual says the bolts should be 150Nm - I dont know much about physics, but that sounds a lot tighter to me. Which is right?
Whats the best way to get the bolts off? I suppose one option is to buy a stack of new bolts in case they do snap, then have them remove the old bolts whatever way they can. What happens if the buggers do snap?
Any advice?
Thanks!
