I have a nice old 262b that had a really slow bucket drift for a year or so. Both Cylinders are new from cat and it still had the issue. Yesterday the drift got bad. As soon as I put joystick in neutral position the bucket starts to curl down. All other hydraulic functions seem fine. So its either 1) valve at joy stick 2) main valve body 3) self leveling valve. Has anyone gone through this and if so how did you diagnose the issue with out throwing $1k parts at the machine....... Thanks in advance
