Changing the right side gearbox oil seal on Twingo 2

Since you will need to fill the oil box at the end of the operation, the vehicle must be parked on a horizontal surface.

Start by removing the universal joint nut with a 30mm socket.

Remove the wheel: Securing the vehicle

Place a drain pan under the box.

Locate the box filler cap and open it.

Using an 8mm square remove the drain plug and let the oil drain.

Cardan

Coupling to the box using grooves.

Fixing the bearing

The bearing helps to limit the bending on the cardan. Here, the cardan is just inserted into the box and the bearing is the only element that prevents it from coming out.

Using a socket and an 18mm combination wrench, remove the 2 nuts and the screw on the inside, then uncouple the ball joint from the wishbone.

If you have difficulty uncoupling the ball joint, you can use a crowbar or a crowbar to pry the arm off while pushing against the stabilizer bar.

Using a 13mm socket, remove the screw and then tilt the bearing support.

Remove the gimbal by pulling on it.

Using a pair of pliers, remove the seal .

Old seal

New seal

Clean the seal area.

Put a little gear oil on the bearing to make reassembly easier.

To reassemble, I positioned the new seal and then put the old seal in place, tapping it with a mallet until the new seal was seated in its final position. You can use a socket instead of the old seal if you prefer.

Using a transparent pipe and a funnel, fill the box with ELF NFJ 75W80 oil. The level is done by overflowing.

The rest of the reassembly is done in reverse order.
