257b lifting hydro issue

i have a 04 cat 257b recently when going into a pile of dirt i have been hearing a banging noise from the right side like a thumping sounds like hydro now the next issue is when i go to lift something it has like no power and you hear a thumping coming from the right side i dont know what part of the hydros to check but please help. The machine used to always lift stuff it would just tilt forward with too heavy load but now it has no power
