Swing manifold would be worth a look first. If you open off the case drain port behind the boom foot and track the machine see does it pressurise the circuit. Had to replace seals on my 312 a fornight ago made a big difference to track power

I just had a 315 b with a weak track and it was low piolot pressure on that side. Just adjusted the set screw on that pedle and now it walks straight. 1/2 turn was difference of 250 psi to 500 psi.
