Dwyane Wade & Chris Bosh: Jam Sesh, Sangria & Matching Trucks ... Best Friends Forever!!

Dwyane Wade bolted Miami for Chicago ... but he's still kickin' it off the court with superstar ex-Heat teammate and BFF Chris Bosh ... bro-ing out at C.B.'s Malibu mansion.

The former teammates linked up in the 'Bu Wednesday for some quality man time ... gettin' in a bunch of activities, from jammin' out on the drums and guitar to hiking (while their wives tagged along and drank sangria).

If anyone thought there was a drop of bad blood between D. Wade and Bosh ... this video surely puts that to rest.
