propshaft center support bearing

[moots]

had the center support bearing (csb) replaced last week.took 6 hours all in to replace.paid the shop to press the csb onto prop shaft.the exhaust (from header) and heat shield needs removal.

so,i need your thoughts as to why we need to pre-load the csb after fitting the prop shaft to the car.

6 hours? takes me 2 in my driveway, and one more to drive to the shop to have the bearing pressed. I'm not sure why the bearing needs to be pre-loaded, but it does otherwise it only lasts about 10k miles if that.

Took me about the same strung out on no sleep and doing control arms and tie rod ends, subframe plates and new exhaust hangers at the same time argh.
