Try repining your connectors first for the Claw issues. It's much easier to do than removing everything. I purchased a DM about 3 months ago that worked perfectly, but was INCREDIBLY dirty. I tore it down completely, cleaned everything, put it back together, and then had nothing but nightmares with claw issues for about 3 weeks. It turns out that many of the pins in those old connectors go bad. I even had 3 or 4 instances where connectors with 2 wires going out of them (in the same pin) had a short in only one of the wires. All in all, I ended up replacing or repining about 7 connectors, before everything was back to 100%.
