I have a cat 287b 2007 have had cab up many times till now. front bolts out but cab wont lift up. It is not the latch as it is moving freely. I believe it is the 2 bolts top rear that the cab pivots on, they seam to have a rubber piece in them and I cant get the bolts out anyone have this problem. Or could it be something else, I removed the lift arm not the problem.
