Have a 2019 T740, 980 hours, purchased 4 months ago and just noticed some play in upper lift arm. Not much but any usually turns into a lot quick. Haven't bought the service manual to see what if anything is replaceable. Everything had been greased well. Seems like low hours for pins to wear out. Also the bucket squeaks when tilting. Everything in very well greased as well. Has a very high chatter when tilting bucket.
