I am having the same issue. On my 18 520l also. My failed in November coming home also. I'll probably have to change everything. Looks like I tore up the brake caliper as well. This is going to be the second one that I have replaced. This time I am going to so it myself. Very informative video thank you

The brake caliper is torn up from keeping the wheel from coming off the trailer. When it is a complete failure, the brake caliper is the ONLY thing keeping the rim and tire on the trailer. If you ever fail to release the manual brake release and travel very far, the heat from the dragging brakes will cause premature failure as well. Not that I have ever done that! LOL

It should be very close to the 9:00 or 3:00 position if you did not pre-mark the location. You might try pulling the tire off the opposite side and measure the center of hub up to the fender to try to get the closest estimate. There are many teeth on the spline so it is very minor adjustment with each tooth. As long as you put the bolt through on the spindle you could put the rim and tire on and lower the jack to see the actual height in the fender well.

@@davidkilbury1689 good ideas. Thank you. Great vid by the way. Also did you leave the arm flush with the out side of the axle ? Same thing I can look at the others just wondering how you did it is all

Outstanding video series. Most clear I’ve seen on youtube

Been reading a lot about the grade (5) 5/8 x 4 1/2 torsion bolts that come with the torsion spindle and throwing them out and replace with grade (8) 5/8 x 4 1/2 because the grade 5 are known to stretch and come loose which will put a strain on the hub and cause bearing and tire wear.

I have not heard that myself. I have not had any issues with loosening, but you must use lock tight during install and tighten to torque spec.

Jeff, Take off the grade 5 bolts and throw them out, they WILL stretch after time. Replace them with all GRADE 8 stuff. I did it last year because I had a tire wearing on the inside bad, afetr replacing all mine with grade 8, NO ISSUES at all. It's not hard to do and you will not regret it. It's a must in my book
