Ok I have been worried about my fan hub ever since Silver had his very expensive failure. I had planned on wiggling into the engine compartment but I can't get in there. Between a really bad knee and my fat ass it isn't going to happen.
I decided to see it from the top. Easier for sure. There are 4 square head long screws that hold it in. 2 on the back panel and 2 on the floor panel. Remove them and buy new ones because they will strip out. Pull the back panel out from the top and use a pry bar to push the floor panel to the rear of the MH. It kinda all comes up at the same time. What holds the floor panel in is the two screws and two brackets that fit under the floor.
You can see the fan and the back of the radiator much better than I remember.
Be careful not to deny the aluminum trim. I did not to bad but if you use a wide pry bar to push the floor panel to the rear it should not dent.
Not a bad job at all. I will say that I do not have the socket to check the bolts on the hub. They appear tight and secure but that is just from feeling it and trying to push it. I feel confident that it is good.
Hope this helps.
