I had my CV joint replaced a few months ago. When they fitted it the clip was done up tight enough and it spilled a lot of grease. Fortunately I spotted it quickly and took it back where the repacked it and retightened it.

Recently the car has been making some weird noises when accelerating at 40-60mph and some accompanying clicking on full lock, after having a look I noticed this (see picture). There has been no extra grease come out so what has happened to it? The garage has suggested that it might not need a replacement. I cant see how it doesn't but have no technical knowledge to back up my assumptions. can anyone shed any light as to what is going on with it?

On a side note, I have noticed that the ball joint boot has a split. I have been told that the rubber boot can be replaced. Is this normal practice or would it be best to replace the whole ball joint considering that the part is less than the labour to fit it?
 
Yes 'boot' can be replaced...though I doubt that will fix the clicking. If the ball joing has a split in rubber then realistically that ball joint need changing.........and whilst you are there, may as well to the one on other side.
 
Agree with the above. You can change the boot but if it let the water, dirt and dust get in the joint, this is where you might be getting the clunking noise from.

That's my thoughts. If its clicking, it sounds like it is too far gone. Could I ask why the boot has done this? Is it due to lack of grease?

Just to confuse the matter, could the clicking noise on full lock be the ball joint?
 
If CV joint was replaced a few months ago and is bad again already (leaking boot maybe) then I would suggest should be replaced for free. Was this a MB garage that did repairs ?

Hard to say without seeing/hearing.

That boot was put on incorrectly otherwise it wouldn't get twisted like that.

I'd insist on the new joint.
 
Cv joint is common, buy genuine or gkn.

That boot that has been fitted is a cheap nasty one, that's why it's all twisted.

I'd imagine the bottom ball joint boot was damaged when the cv boot was replaced (this isn't necessary) it can be replaced by removing the strut bolts.
 
This CV joint has caused so many problems. I have a split boot 2 years ago replaced. The indi fitted it incorrectly leading to a fail. I took it to a different garage who also fitted it incorrectly and the clips fell off. They refitted it and all was fine until 2 months later when it starts clicking. They refused to accept fault so in the end I tried another indi. The one they fitted lasted a week. They replaced only for that one to be faulty from the start. It was later discover to be a faulty batch. They tried a different brand, the one I have now. They fitted that too losely and it spewed grease every where. Took it back straight away where they repacked it and tightened it.

Now this. Garage is questioning whether it's my car that's at fault and suggesting that the CV joint is fine.:(
 
Is it worth buying the correct one from MB? At least it will fit correctly
 
Your having a ruff deal with what is a fairly simple job, where are you based? Is there not a Indy on the forum close to you?
 
I'm on the West Yorks/North Yorks boarder. The garage has come with a good reputation. There is a Mercedes specialist nearby but they aren't that far from dealership prices plus I have paid £130 for it to be fixed so want them to fix it really.

I see that GKN or genuine have been mentioned, is there any reason for this, for example, are the CV joints on the B class prone to failure with other 3rd party parts?
 
A/b class are prone to failure anyway, I recommend gkn or genuine purely based on quality.
 
Garage is saying that it needs a new shaft. They showed me that there was a lot more movement in that shaft compared to the passengers shaft. I'm assuming they should be the same. They are getting someone to see if they can recondition it due to the difficulty in sourcing the correct one (after market) and Mercedes wanting around £700 for a new one!

Apologies if I missed it. What car is this on. I have a pair of CL55 shafts.

Because at full lock the ball joint is at greater stress and the noise you hear is the ball rubbing against the worn housing.

Sorry, so the click could be the ball joint? Does it sound similar to a CV click?
