I have a LA 524 Loader, on my l3800, with broken loader arms, I have re-welded the problem a few times, with limited success. I've been quoted $2000 for a major re-weld or $1200 for a new set of arms from Kubota. My thinking is to go with new arms, hence my questions. 1) Has anyone done this before, are there issues I should be aware of? 2) Are the bushing/pins easily remove and replaced? 3) Will I require new bushing/pins or can old ones, be reused?
