Have you contacted
Stuart's Services in Elkhart IN. yet? They are the largest HWH service center outside the HWH factory.
If you remove the jacks and the associated control boards you slide might be rendered out of action too.
First determine which model
HWH leveling system you have; and the
model slide system you have, before calling.
And yes, PC boards often may be repaired by a patient knowledgeable person with a steady hand..
