This is maybe of interest to those of you who intend to do some work on some VAG cars.....
Had to replace a rear hub bearing on a Seat Leon the other day (ABS light on, sensor fine so it was the magnetic reluctor on the bearing itself that had failed). The bearing and hub come complete.
The hub bolt is actually a 16mm spline bolt, and is ferociously tight. I was using a 16" Halfords Professional breaker bar, and couldn't shift it.....I supported the breaker bar and extension on a trolley jack and stood on it - promptly shearing the bar knuckle clean off
Fortunately a long pipe on a Britool ratchet managed to shift it, but I was convinced that those splines were about to strip - and then I'd be in real bother!
The caliper bracket also uses these spline bolts (14mm this time), again, fiercely tight and access was poor.
If you come across these spline bolts, heat them up if you can to soften the locking compound, and always drive them in to the bolt head before trying to undo them. If the splines strip, or the spline bit cams out you'll get hours of fun trying to shift them!
Have a good day everyone
