What type of ball joint puller do I need to rent for a 2005 Buick rendezvous?

Ok, go to your local auto parts store, rent an axle puller, or you can try a prybar.
The axle puller is a safer way to go. It looks like a dent puller or slap hammer.
Good Luck

If the lower ball joint is riveted to the lower control arm you will be way better off replacing the entire control arm. They are available at your local parts store and are not that much more.

jack up the vehicle. remove the wheel, remove the nut from the ball joint. remove the stabilizer link from the lower control arm. strike the knuckle where the ball joint goes through with a large hammer until the ball joint separates from the knuckle. Remove the horizontal mounting bolt, remove the vertical mounting bolt, remove the lower control arm.

After removing the nut for the ball joint with a pry bar pry diwn on the control arm with a good hammer hammer on the knuckle where the ball joint goes into until it comes apart. Or simply use a fork to separate the two.

JACK THE CAR TAKE THE TIRE OFF LOOSTEN THE CENTER NUT YOU MIGHT NEED TO PULL THE CALAPER OFF TAKE THE NUT OFF THE LOWER BALL JOINT PUT A BLOCK OF WOOD OR FOLLR JACK UNDER THE LOWER CONTROL ARM KEEP ABOUT AN INCH FROM IT EATHER HIT THE SIDE WITH A HAMMER OR USE A BALL JOINT PULLER YOU CAN RENT ONE FROM AUTOZONE ONCE THE LOWER CONTROL ARM IS LOOSE LET THE FLOOR JACK DOWN PULL THE ASSEMBLY OUT TILL YOU GET ENUFF CLERANCE TO PULL THE CV JOINT CLEAR AND GIVE A GOOD YANK AND EVERY THING WILL COME OUT OF THE TRANS /// REPLACE IN REVERS

You need a steering wheel puller. You can borrow one from autozone or a tool rental place.

It is the universal joints........Hope this helps.

Ride height, struts , ball joints , contro arm bushings,
worn tires (out of round). The vehicle is 6yrs old a wheel alignment is in good order.

you can rent a joint separator at auto zone . they return your money after you bring the tools back. all else is pretty cut and dry on replacing the ball joints.

Is this vehicle front wheel drive..? If it is then you have a CV joint about to collapse !!! The CV or Constant Velocity joint allows the drive from the transmission to drive the wheel during turns. The joint is made up of balls and sockets and as the sockets wear,they elongate. Eventually, the balls try and lift out of the sockets and this is the popping sound you can hear.. Replace BOTH joints because if one has failed, the other one will too. If you don't replace them, they can snap and you may lose control and crash !!! Replacing them is relatively easy. Remove the drive shaft from the transmission or gearbox by releasing the large nut at the outer side of the disk rotor. release the upper ball joint which will allow you to pull the shaft out of the rotor and the transmission. The joint is held onto the shaft by an internal circlip and a good tug on the joint will allow it to slide off the shaft. Refit the new joint and refit the shaft. Make sure the nut at the rotor end is TIGHT!!!! and make sure you refit the locking pin if it has one..
