C70 crack when reverse.

[S402002]

Hi ive got another problem with my c70. It does crack when reverse. Its not when i switch the gear just while driving reverse 1 bang and its ok. I have 2 new driveshafts and doesnt help. Sound seems to be like something isnt tight enough and make that bang. But have no clue whats that?

Yep, it's axle ping, very common on our cars. Usually triggered when someone has CV boot/driveshaft work done.

Undo the drive shaft bolt from the center of the wheel hub (no need to remove the wheel) put some strong Locktite inside on splines then torque the bolt up correctly (can't remember spec off the top of my head).

Don't drive or move the car for 12 hours while it sets.

Jobs a good'n!

I was under the impression that new bolts had to be used once they had been removed?

If they're old then yes.

If OP has not long had new driveshafts installed they should be fine to reuse.

I would avoid STRONG loctite like the plague , simply because when driveshaft work is needed you will never release the joint from the hub

50 ton press & oxy-acetylene almost failed

sorted out! thanks guys!! that was old axle bolts!!! thats odd as i did replaced that driveshaft in local volvo independent specialist and look what they have done! they used different bolt and way shorter than original!!! they charged me just for labour 100£ to replace it and look what they did! all ofthe noises from underneath and gearbox when change from park to drive gone even chasis shake gone as probably driveshaft wasnt tight enough and made rhat noises and caused vibrations !!!!
