guibo & DS center bearing - how hard?

[funcrew]

It sounds like there's a bucket of rocks banging around under my floorpan. Is that probably the guibo? Can it be replaced without pulling the rusted-in-place exhaust? Same 2 questions for the driveshaft center bearing. How hard is this project?

Thanks

Pain in the ass with exhaust and heat shields in place. If you are mechanically inclined it should only take a couple hours.

EDIT:the woodpecker in your floorpan sound is most likely csb

In almost all cases, a failure of the rubber mount of the center support bearing will be caused by binding u-joints in the drive shaft, which sounds to be the case here. You can just replace the CSB, but it won't last long unless you also replace the drive shaft.

i just did my centre bearing and guibo on the weekend i am a helicopter mechanic and it took me 5 hours... with many beer and smoke breaks mind you. my centre bearing was so bad the metal hoop around the rubber shock mount was cracked in half lol

I was wondering what the vibration that i still feel is so ur sayin it's prolly the u joints binding jlvie? when i had the ds out they felt kinda stiff but arent they supposed to be that way?
