Introduction
Replacement of the 2 Ø66mm bearings (3-hole hubs)
-
-
Immobilize the car and chock the rear wheels
-
Loosen the wheel bolts
-
Straighten the edges of the universal joint nut using a small flat screwdriver + mallet
-
Loosen the universal joint nut using a 32 socket while the car is on the ground
-
Raise the car using a jack + secure the vehicle using jack stands
-
Loosen the wheel bolts. Remove the wheel. Unscrew the universal joint nut
-
-
-
Loosen the upper caliper screw using a 19 wrench.
-
Loosen the bottom screw using a T40 torx key
-
Push the piston back slightly to slide the caliper without removing the pads.
-
Remove the ground screw using a 10 wrench.
-
Remove the caliper and attach it so as not to strain the various cables.
-
-
-
Remove the steering ball joint nut with a 17 mm wrench.
-
Using the ball joint remover, uncouple the steering rod
-
If there is no ball joint puller, it is possible to "tap" on the axle to remove the ball joint (/!\ risk of damaging the thread)
-
-
-
Loosen nut with 16 wrench or socket and remove screw
-
Using a tire lever, extract the ball joint axle
-
Position the tire lever so as not to damage the universal joint boot.
-
Disconnect the universal joint from the hub assembly
-
-
-
Loosen the 2 upper screws of the landing gear leg using a 13 socket wrench.
-
Remove the landing gear leg and store it to avoid damage.
-
-
-
Remove the screw using a 6-sided wrench
-
Store the disc to avoid deterioration
-
Using pliers, remove the circlip.
-
-
-
Install the hub firmly in a vise. Using a socket of the correct size, tap the bearing.
-
Be sure to stay vertical so as not to damage the rocket.
-
Retrieve the rocket and remove the cage and balls
-
Using an extractor, remove the ring from the bearing.
-
If you don't have an extractor, heat the ring with a blowtorch and gently lift it using a chisel.
-
-
-
Reposition the hub on the vice. The bearing ring must be removed from the side of the circlip. Position a mallet or socket on the bearing and use a second mallet to tap it out.
-
Be careful not to damage the hub cage
-
Clean, degrease and wipe dry before reassembly.
-
-
-
Clean the bearing and make sure there is no dirt on it. Grease the bearing well on the outer surface.
-
To make assembly easier, you can leave the bearing in the freezer (be careful, the grease will crystallize).
-
Check the dimensions of the new bearing before reassembly
-
Using a mallet, put the new bearing in place.
-
It is imperative to tap the outer and inner rings in the same way. Use the old bearing which will allow for perfect support
-
Check that the bearing is properly inserted up to the circlip groove
-
Replace the new circlip
-
-
-
Clean the rocket and grease it
-
On the vice (or mallet in the photo), place the old bearing under the new one. This prevents the cages of the new bearing from coming apart. Without this support, when you push in the spindle, you risk coming apart the bearing
-
Push the spindle firmly into the axle by tapping it gradually. The new bearing must always be resting on the old one.
-
-
-
Follow the previous steps in reverse order
-
Clean the various elements before reassembly
-
Reposition the landing gear leg in its location and the universal joint in the hub in accordance with Etape 5 and tighten the 2 nuts
-
Reposition the triangle, bolt and tighten according to Etape 4
-
Reposition the steering rod and tighten the nut according to Etape 3
-
Reposition the disc, tighten the screw, install the caliper and tighten the 2 axles (add thread lock) in accordance with Etape 2
-
-
-
Tighten the universal joint nut
-
Deform the nut at the notch of the universal joint
-
Tighten the wheel bolts
-
Remove the jack + the candles and finish tightening the cardan nut and the wheel bolts
-
The disassembly phase (preparation) is simple to moderate, however, the extraction of the bearings and the reinstallation is delicate and requires a lot of attention.

Hello
I did everything in the same order as I used a press but I have one side that is veiled so I have to start all over again!

Hello, I followed your tutorial from start to finish, thank you very much, no problem. However, when tightening the hub bolt, I noticed that I have a little play on the rim, whereas with the old bearing I had no play. Do you have any idea of the problem? Kind regards…

Good morning,
Glad this tutorial helped you. For the game, can you detail or better put a photo (if the site allows it)?
In fact, the bearing is fitted for the outer ring on the landing gear leg and for the inner ring for the spindle, it is therefore not in contact with the rim.
The bearing is fitted tightly and there should be no play. Were you able to position the circlip? If the circlip is positioned, the bearing is correctly positioned. Afterwards, make sure that the spindle is correctly pushed in. If you did not press on both the outer and inner rings at the same time to position it, the inner rings may have moved apart. This happened to me. By tapping gently everything came back into place (and the balls did not move). This is the reason that I see. I will let you look and come up with more details
