My L2501 has an annoying squeak where my 3pt turn buckle stabilizer (Kubota calls it a check chain) attaches to the ROPS bracket on the rear axel(see pic). The clevis is squeaking. I’ve tried dry lube and a little grease. Both fix it temporarily, but only for a few days. I’ve tried tightening and loosening the sway of the 3 pt by turning the turnbuckles but neither seem to help. Any suggestions for a long term or permanent fix? Thanks.
