I have now replaced the stainless steel bolts M8x70 connecting rim halves, with higher quality AN5-24A bolts. I had earlier problems with seized threads on the SS bolts. All rims are now adjusted again to minimize wobbel. Wheel bearings are adjusted and nuts locked. Axles torqued to main spring and locked. At the same time I replaced AN3-11 bolt at right hand brake-pump support. New bolt AN3-13.
