You can use a tape measure or calibration blocks, old broom handle cut up works wonders
Are you really asking for a friend?
Yeah, really.. I feel compelled to help as its my fault he got a 38, cos I said how great they are and they don't rot. He's had lots of problems but minor mainly except for bad rot in the rear crossmember.
That don't work for me?
Me fone sez can't be safely opened or summit.
My computer is always looking for ways to dob me in.
Most likely...either use a stick to measure from hub cap to the top of the wheel arch (easier than remeasuring with a tape the whole time), blocks are the fool proof way and save lots of running around the car (in lieu of crawling under the car, of course). Although assuming you also have your "friend"
to help then the rhythm stick approach shd be fine
The sensors are not precision devices, calibration is always needed when a new sensor is fitted. I always use a measuring stick, much quicker than faffing around with blocks.
