Hello, one of the wheel lugs on my tj magna has broken off. In order to remove the rotor and access the hub I need to remove the caliper assembly, the attachment to the hub and knuckle.I managed to remove the caliper but the two bolts that attach the caliper assembly to the hub seem to be impossible to remove. The manual says 90nm of torque i'm sure I have applied more than this, to the point that one of my socket wrenches actually broke.The two bolts seem to be frozen, how should I go about removing them? Also assuming I get it off how should I go about replacing the broken lug?

Wheel lugs only take 95-100 Nm torque, no way you can break one if you stick to the right torque.

Anyhow . . . .

Lots of force needed to remove those two bolts, probably heat welded or rusted in tight. If you need to buy a new socket, get one for an impact driver, they are unbreakable.

Once the rotor is off, the broken wheel stud belts out from the front, one hammer blow should do it.

A new one just pulls in when you do up the wheel nut. Align the splines when you put it in.

first of all, ratchets are not meant for extreme force. you need to head over to autobarn or supercheap and buy a solid L brace or breaker bar especially made for this sort of application.

get into a position where you can use as much of your strength as possible to put torque on the bolt. dont forget that the longer the tool, the more tprque is applied at the turning point. i used to use a solid L brace, approx 30cms long and a series of long extentions which would usually put it at about 2 foot in length.

spray the nut in WD40 and let sit for 10 mins. do this twice.

protip; when reinstalling the bolts, spray them in WD40 before screwing them in. this will not make the bolt shake loose but will help make it easier to remove next time.

Don't spray calliper bolts with wd40 FFs, most stupid thing I have read in ages

If correct tools are used you won't have issues removing or replacing
