Back To Peugeot 306 Menu

We had to replace the outer cv joint rubber gaiters on both the nearside and offside driveshafts.
I was going to detail the complete removal, overhaul, and reassembly of the front driveshafts, but I lost a lot of the pictures.
On these type of driveshafts the outer cv joint cannot be separated as it is the spider and yoke type. Hence, you have to disturb and separate the 'inner cv joint' in order to replace the rubber gaiter on the 'outer cv joint'. On one of the 306 HDI's I have owned I found I could separate the 'outer cv joint', which made the job so much easier.
These pictures show part of the disassembly of a nearside drive shaft on a 306 1.4i 1995. The offside driveshaft is disassembled in exactly the same way.
On our car, the offside driveshaft gaiter was split and the grease had spilled out. The MOT guy said the cv joint was ok and that it just needed a new gaiter. The nearside driveshaft gaiter was perishing, but not leaking yet. We replaced both gaiters for a total of 7pounds and about 16 hours of work! The offside driveshaft inner cv joint was badly marked and worn on all three roller sliding surfaces, but we just replaced the gaiter in order to get it through the MOT. We will replace the driveshaft at a later date if the car turns out to be a keeper.


↓ This is the 'outer member cover' secured in the softjaws of the vice.
The 'outer member cover' is peened over and thus secured to the 'inner spline shaft'.
Note, the 'outer member cover' covers and protects the 'inner cv joint'.
I put some thick tape over the 'inner spline shaft' to go some way to protect it.

↓ The 'inner cv joint' gaiter is attached to the 'outer member cover'. I don't think they can be separated?

↓ The metal of the 'outer member cover' is carefully prised out using a blunt screwdriver and a hammer. Take your time doing this, there is no rush.

↓ The 'outer member cover' slides off the 'inner spline shaft'.
Do make sure all the metal is prised out as you do not want to rip the o-ring as you slide it off. Slowly separate the two parts. Do make sure you put marks on one of the roller shafts and on the corresponding slideway on the cv joint, to enable the joint to be correctly reassembled.

↓ As you separate the two parts a spring will fall out. Be sure to note the orientation of the spring.
The plain end of the spring fits in the 'inner spline shaft' housing.
The thrust cap on the spring bears against the end of the 'tripod' joint.

↓ The 'outer member cover' and 'inner spline shaft' are now separated.
Note the o-ring in the groove on the 'inner spline shaft'. This stops the grease oozing out.
The manual says to replace the o-ring. We are doing this job on the cheap, so we re-used it and backed it up with a smear of silicone sealant.

↓ The 'tripod' that holds the three 'rollers' is attached to the driveshaft by a circlip.
The 'tripod' fits on a spline on the driveshaft.

I used a carbide insert to scratch a mark on hardended driveshaft, and filed a corresponding mark on the hardended 'tripod' in order to preserve the orientation upon reassembly.

↓ I used a 3 legged puller to pull the 'tripod' off the spline.
This did not require much force at all.
Once the 'tripod' is off you are pretty much home and dry. With the 'tripod' off, you can get at the outer cv joint gaiter and remove and replace it.

Unfortunately I lost the rest of the pictures of the disassembly and overhaul.
If you have got this far then the overhaul and reassembly will be apparent.
