trailer stub axles

[bazz]

lads was going to adjust my trailer brakes the weekend only to find one wheel about to depart stub axle and all its an sbs trailer and the stub axle is bolted in with a 17mm allen key bolt from behind if anyone is doing work on one of these before the summer i suggest checking the bolt as well as the bearings it was by chance i spotted it as i had replaced all brakes and bearings last year
