I had to remove the rear half of both rails to slide in the cross members. It wasn't bad at all.

Pop the plastic cover (since I wanted to keep it, not damaging this piece was the hardest part!)

Remove 2 bolts. (If you want to slide a rail end, you remove the endcap with one torx screw)
Repeat other side.
Repeat for front.

Even with a new rack, your limit will be how much weight your roof can take. Although if you haul a canoe, you have to worry more about upward force, not downward force (weight).
