The control arm has to be replaced . for a 1995 sentra it costs 172$ at the dealer and on the web it available for 100$ each .
Most likely it's a CV joint.
could be a contant velocity joint
Remove the u-joint from the back of the transmission. Remove the transmission mount bolts. Remove the transmission bolts. Remove the linkage. The transmission will slide backwards and can be removed.
Drop gearbox down from cross member,Use a power bar & several long extentions with a knuckle joint attatched!
you need a pickle fork. use a this and a hammer to wedge the ball joint away from the control arm.
Its just above the right inner CV joint, plugged into the bottom/ back side of the engine block. You can only get to it from under the car.
Remove wheel hub, remove the 4 bolts holding the ball joint in place, heat it up with a torch, then bash the crap out of with a hammer til the ball joint pops out.
I know you will need a pickle fork or ball joint separator for the joints, other than that i think it just unbolts so sockets and wrenches
The Nissan Sentra is a Front Wheel Drive(FWD), and as such has no u-joint. Since the engine is transversely(sideways) mounted, there is no driveshaft to connect from the transmission to the axe housing. Instead directly fromt he transmission outdrive there are a pair of halfshafts which go out to the wheels. Each halfshaft has an inner and outter CV joint. CV Means Constant Velocity. They are smoother in operation, and can be turned into a deeper arc then can a u-joint usually. As for why CV joints are not used in place of u-joints everywhere t's a matter of economics. u-joints are MUCH stronger, and cheaper to manufacture, but they will not work in a FWD situation. Rear Wheel Drives drivelines are subjected to ALOT higher torque multiplication then any front wheel drive is capable of. While it's possible to get extreme amounts of horsepower out of those little engines, it's the torque that really breaks things, not the horsepower.
