 |
|
Have been hearing an annoying gristle sound from the rear of my 1970 IRS Beetle when coasting (with or without brakes depressed). Crawled under to check the four CV joints and detected some play in the the driver side outside axle. Pulled the axle and removed the CV joint. The balls are pearly smooth but the outside races have distinct grooves - all six. the inside races too. Here is a picture.
What do you think? Bad enough to replace? I can afford the $65 from jbugs but am trying to keep the China to German part ratio to a minimum. Any advice here would be welcome.

| Cannot tell from pics how deep are grooves? If really deep and you are bucks down look for good used buy the new boots and rebuild. Lately I get the impression people are afraid to tackle this job. If money is not a concern buy the Lobro German replacements. On the extreme you could upgrade to the larger type 2 CVs. There are still piles of good used cv joints gathering dust |

I'm not sure how compression works.
Turbos don't produce torque, they produce HP. Instead of torque.
The real problem with NA engines is you don't hear the nice whine of the turbo as it spools up.
Before I commit, I'm going to do more research because I don't really know what piston rings are. |

I'm into the same job. Bought all nos cv joints. I would go ahead and replace them since you already have them out. There seems to be plenty of quality joints around.

They are defective....Orielly's has lifetime replacements the complete shafts. I have them on my car for oh um eight thousand miles. No problems.

| Good rule of thumb is if you can feel it it's shot. I would shop around for some Lobro CV's |

the empis offroad cv's are some of the best made....I havent a clue as to the std stuff.but I would relay worry about it but i would make sure everything is right. for some reason those dont look like something was right... but if thats all assembles right and thay dont travel any more than that you could flip it and have a new serface to wear out...   witch if I had to have it going and didnt have time to wait I would do.(if thats flip able I dont recall but I think it is)....brain fade....too many cv's rolling around in my head. and I aint no cv exspurt.... |

On CVs if you can even see grooves they're finished.
Ya mark, I've flipped CVs before to get a few more miles out of 'em but it's only a bandaid. Works the best on vans where the axle angles are a little greater.

I wonder if a "Loebro" is the same as a Lobro or is that how you say hello to your bro

| The boot for the inner passenger side has a huge tear in it. I will need to replace it. Can it be replaced without having to take the shaft or trans out? What would you recommend for a 71 standard beetle? |

While I do believe there are split boots available for type 1 CV joints, they usually don't hold up well at all so I would recommend sticking with the original one piece style boots. As such, you will need to disconnect the axle shaft at the inner end at a minimum so you can pull the CV joint off and replace the boot; if you haven't cleaned and repacked the CV joints in quite some time, this would be the perfect opportunity to do so. Removing the trans is not required.

Unfortunately, you’ll need to remove the CV joint. It’s not that difficult a job, if you have the proper tool to loosen the bolts.
Be sure to clean out the bolt heads squeaky clean before attempting to remove them.
You have to remove them because you have a tear and you need to check for damage to the joint. Also, it’s a lot easier removing the joint when the shaft is placed in a vice.
