Thank you very much for the detailed information.
What can happen if this CV Joint won't get fixed?
Can anything serious happen? Can I make long jorneys? I have to drive to the airport on saturday which is 60 miles one way.
By the way. I'm already driving with this noise for about a week now.
It doesn't really change. Doesn't get worst or anything.
The funniest thing is that you can't hear it from outside. You can only hear it slightly from inside of the car.
What could be the average price to change the CV Joint?
Hopefully it's going to be less then 100 quid
Also, If I will change it. Would you recommend to change both front cv joints at the same time? Just in case you know...
Or there isn't really big point doing it?
Yes you can continue driving but this is an issue that will become worse over time therefore the sooner the better.
There are two ways about fixing a CV joint, you can either purchase an entire drive shaft that comes with the CV joints inner and outer already installed, straight swap. or you can purchase a CV joint kit. The kit consist of bearings, new boot, small items specific to that cv joint plus a tube of oil to refill the boot.
Looks like this
Euro car parts has it listed from £50 to £80 for an outer cv joint kit
An entire drive shaft is listed £60 and £90 left and right. The left side is shorter than the right hand side, they are both connected to the differential... that rotates both wheels in the same direction at different speed.
I have never used a CV joint repair kit before but most mechanics would say it's better to replace the drive shaft than do a repair (I think this is because it's easier...) otherwise i would believe if the repair is done correctly it's no better or worse than an entire replacement.
These parts sold by parts company are not brand new they are all reconditioned parts cleaned and replaced worn out bits sold as new, the only place you could get a true brand new drive shaft is ford., don't be put off by this though alot of car parts are reconditioned nothing is wrong with it either hence the cheaper prices compared to ford.
You do not need to change both at the same time.
If the boot is badly damaged with no oil at all and bearing destroyed in worse case scenario the joint can pull apart and then your wheel falls off disconnecting from the suspension, wishbone taking the wheel hub and brakes don't let that scare you though if yours was this bad you'd know, the car would wobble and drift about and knocks loudly.
Firstly identify the true issue so far its only an assumption that the noise is caused by a drive shaft.
PS, if the bearings are badly damaged you cannot use a repair kit in this case only a new drive shaft to fix it.
Also i don't know how old your car is or it's condition but when changing a drive shaft the bolts can be rusted and seized up, in this case heat may need to be applied and decent tools used to avoid rounding off the bolts in other words let a mechanic do it
