Had the steering go on the 124 last summer late in the year. Took the unit apart and rebuit it. New bearings and worm gear stud. Everything new. I packed it well with grease and it worked real well. I put it back in in hopes to use it with the blower in the winter. Didn't need it then as the winter was mild and it wasn't used. So off with the blower and back on went the mower. Have been using the mower up till today and again having issue with slop in the steering. Then it went just like that. I know I have it now apart again and the stud for the worm gear is completely gone. The grease looks to have all the metal from the stud in it. What has gone wrong to have to rebuild this again so soon? I've not used it that much this spring to warrant it was over use that's for sure. It does ride in the truck when not in use at times. Could that lead to this issue? I know have to rebuild this all over again. This time though it came agart real easy. Guess I know what I was doing. Any of you have any ideas what is causing this and what to look for? Thanks.
