    Lull 844 (1970’s – 80’s?) tower (it raises forks 7’ up & down) shuddering and even crashing down.

    I think it was old grease too! I had leveled the tension a while back and it still is good as can be. I had removed all gunk possible and used white lithium spray lube & silicone instead; it's getting better all the time; no crashing now - just occasional shimmy now which is not an issue...

    Generally happens after lifted 2’ up when going back down. Telehandler tower wear surfaces was cleaned, chains straightened slightly (doubt it needed) it still won’t lower the forks properly after hoisting a load; chains go loose and forks stay put. Tried cleaning all old gunk off traveling...
