Today I will describe how the symptoms of a failed rear half shaft bearing look and tell you how to fix it. Also, I'll touch on the topic of replacing the parking brake pads.
So, let's start.
During driving, I noticed a squeaking sound coming from the back part of the car. At first, it wasn't clear if it was friction against the housing, a stone under the brake pad, or something else. After 500 km, the noise changed from barely audible to a noticeable loud hum — time to go see my friends at WorksGarage!
Raised the car on jackstands and concluded that the right rear half shaft bearing had died.
Here's how it sounds
Thank the engineers at Nissan — removing the half shaft isn't too difficult, but finding replacement parts is another story.
This is a list of part numbers we need to purchase:
— 43215-P0100 — half shaft bearing
— 43232-P4500 — seal
— 43084-61001 — retaining ring for the bearing
Based on information from parts websites, we determined that this particular bearing was used in Cedric cars from 1980 to 1999, so finding a suitable part shouldn't be difficult — there are plenty of originals and alternatives at reasonable prices, BUT
DO NOT BUY under any circumstances the repair kit by OPTIMAL with number 962684 — they actively try to push this product on websites, but this kit does not fit (the bearing and retaining ring in it have a smaller diameter). Because of this misinformation, I lost an entire day!
In the end, I bought the original Nissan bearing (see part number above).
You can also get the seal and retaining ring in originals, but you'll have to wait a week or more — since I didn't have that much time, I found alternatives:
— 08R8 — retaining ring by FBJ
— N2148 — seal by Musashi
The disassembly process is as follows:
1. Jack up the car.
2. Remove the wheel.
3. Loosen two bolts that hold the brake caliper (size 17 key).
4. Remove the brake disc. If it doesn't come off by hand, use special holes in the disc and screws inserted into them to push out the disc — be careful not to overdo it; screw in slowly and evenly so as not to strip the bolts.
5. Detach the parking brake cable and remove the spring.
6. Loosen four bolts that hold the hub assembly/drums (size 14 key).
7. Carefully remove the half shaft.
The process of replacing the bearing:
1. Use a grinder and cut the lock ring and remove it.
2. Remove the bearing. My bearing was quite badly damaged, so I had to remove it in pieces. If the bearing is in better condition – you will have to struggle: use a puller or chisel out the bearing.
3. Install a new bearing in place of the old one using a bushing and hammer - do everything very gently.
4. The whole trick in installing the lock ring. It must be heated very strongly (metal expands when heated) and then mounted on the shaft. When the lock cools down (the metal contracts when cooled), it will be firmly seated on the shaft. Don't forget to let it cool down.
5. Remove the seal from the differential and replace it with a new one. Don’t forget to grease the inside of the seal with oil so that it doesn’t get torn off at first start-up!
6. Don't blow out the hub gasket and put it back in place, after which reassemble everything in reverse order!
After removing the brake disk, I found that the parking brake pads (drum mechanism) were falling apart - the pad had separated from the shoe.
Therefore, I had to buy new drum pads as well, fortunately, I came across an original set at a very reasonable price!
Part number of parking brake pads — 44060-V0329 (the kit contains four pads on both sides).
I described the disassembly process above, now let's focus on how to disassemble the drum mechanism and change the pads:
1. Find a rectangular washer between the pads at the bottom and remove it using an Allen key.
2. Remove the lower spring with a screwdriver.
3. Remove the center operating mechanisms of the pads (one each on the right and left). To do this, press down on the spring until the upper washer comes off the "soldier".
4. Remove the upper spring and the central tensioner.
5. Install new pads and reassemble in reverse order.
A couple of tips to make your life easier:
— Start pad replacement with installing the lower spring and rectangular washer
— The second step is to install the operating mechanisms
— Install the tensioner after mounting the upper spring
— Don't forget to adjust the tension after replacing the brake disk. To do this, remove the rubber plug at the back of the drum mechanism and use a short Allen key to turn the tensioner.
