What symptoms would my '71 display if I had a problem with my CV joint?

I think I know the answer but I may be entrenched in my years of experience with water-cooled cars as opposed to the 20 months I have owned my Super.

Hi,

Constant Velocity Joints make a knocking sound when they are worn...

If the wear isn't too bad... no worn grooves etc...

You can repack them with Lithium based Moly grease...

which is blackish and sticky and can stop the knocking sound as the wear contact is taken by this grease.... Don't use any other grease for this purpose.... It can also be used for wheel bearings - front & rear - and can stop further wesr of bearings too....

I have used Lithium based Moly grease for many years , even on Front Wheel Drive Constant Velocity joints.. and it also stops them from knocking...

especially when turning....

You should also use this grease in ball joints or tie rod ends if they have grease nipples in them... and on the front torsion bars in standard beetles..

You will have to dismantle the CV joints and clean them up with kerosene or something similar... to check the wear on them.. they will go back together... it can be tricky though... and they only go back onto the axle one way...

I get a knocking a noise at certain times in fourth gear.  I heard it softly a couple of times in third.  I thought it might be a CV joint from my experience with water-coolers.

 

Thanks for the detailed answer.  Its fix is on its way.

You might want to renew the external type circlips that hold the contant velocity joints onto the axles...

They seem to be made of mild steel and when they are pryed open to allow You to take off the CV Joints.. they stay in that position.....

So, they have to be either renewed or closed up slightly with a hammer if You need to reuse them....

I found the same thing with front wheel drive CV joint circlips...

they were also very soft steel....

Glad to be able to help...

I pulled apart 12 cv joints to find 8 good ones - 4 for My Son & 4 for Me..

I put it off as long as I could.... until My Son needed His 4....

I did find We had two different sorts of CV.. some had larger balls than the standard type... Maybe from a type 2 ??  but all the other dimensions were the same....

I really hate that grease... I now use disposible rubber gloves.... even then I manage to get it on My clothes... and it doesn't come off... or at least the black marks never come off.....

The CV joints seem to fall apart rather easy...  but getting them together takes patience and a bit of luck....  that is without the grease..

fill the CV with a lot of black sticky Moly lithium grease and the fun starts... I usually fill them with grease then assemble them....

but the last 2 CVs I assembled them first then pushed the grease into them until they were full of grease.... then pushed them onto the axle & added more grease into the New boots....

I probably used twice as much grease as was needed... but I feel its better to have too much than too little....

Have fun...
