Thanks everyone for there advice,this hitch came with the truck when i bought it 3 years ago.never needed the slide until move to a new storage spot and had to cut it hard to get in, that is when i hit my truck.the hitch slides fine with no trailer on it,I guess i could take some weight off by raising it some my concern would be that i could move the front legs a little and damage them.I think my next step would be to grease the slide rails more i am only using WD40 now.my model is 70540 same as that last post that they mentioned to get the pins in the right way which is so true I did that once thanks again
