good idea. And no I didn't notice any oil leaking at all. |

If it's not the drum/axel, chock the wheels and do the test again but watch the axels moving because it must be a CV joint. I think NAPA has a rebuilt axel with both CV's, lube, and boots for around $100 exchange. Or just drive in tight circles right and left, forward and backwards and listen for clicking, that's a bad CV. |

If it is the CV Joint. How do I know if I need the regular CV joint or I.R.S? What's the difference? |

"I.R.S." (Independent Rear Suspension) is the abbreviation commonly used to denote the double-jointed axle and suspension system in the later air-cooled V.W.s . . . "I.R.S." equipped Beetles use two CV-joints per side . . . four per car.

If the wheel wobbles, as has been mentioned, check the axle nut . . . the drum could be moving on the axle.
If it's not that, could be wheel bearing(s).
A bad CV-joint, in and of itself, will not cause the wheel to wobble. _________________ Jesucristo es mi Seņor y Salvador! |

Google Torquemeister Tool. Very handy for easy removal as well as proper re-torqueing of the axle nuts.
Yes, I know there's the big hammer approach as well. That was in my younger days though. _________________ My 1973 Standard Beetle Build SOLD

Hi.
To get the large axle nut off you have a few options out there for you. First, if you broke a breaker bar, probably 1/2" drive, we can assume the nut is sufficiently tight. I have a 36mm, 3/4" drive socket and 3/4 drive breaker bar and I slide a pipe over it. Its bent but not broken. This is an option. Also, there are available striking wrenchs. I would avoid the cheapo EMPI style but look towards an industrial tool. Very popular in the industry. Finally, there is a tool sold, believe its called a torquemeister, or something like that. As a pro-mech I had the striking wrench, 3/4 drive breaker bar and socket, and a large 3/4 drive torque wrench. This was for use at home or in the field as I had air tools at the shops.
Depending on where you are at in SoCal many others could help with the loosening/torqueing of this nut. Let me know if you need my help.
As far as the CV joints go many can be put back into service with cleaning and a quality moly grease. Good boots too. I've owned and driven CV equipped bug's and bus' since 1973 and have never broken a cv joint or had to buy one. Dealers sold sets of them nearly ever time a mechanic serviced them that exhibited any wear. I personally have two milk crates of type 1 and type 2 cv's that have been in storage for 25+ years. I would suggest looking for a used genuine VW set vs some off shore stuff.
Many times a road test where one gets the cv joints in a sharp angle in an attempt to verify the knocking noise by driving in a circle where you can feel the body movement. It is quite possibl for your cv's to be so completely dry that on take off, from a standing start, could be your noise.
Hope this helps, Bill. |

Harbor freight.com (or in your neighborhood) sell a big breaker bar cheap and free life time replacement if you break it. Torquemeister is the best as it's a multiplier so you can remove highly torqued nuts and retourque them with a small torque wrench, but it is pricey. |

Thank you. I was driving it today and noticed when I'm coming to a stop and I'll hold the clutch and brake till I stop all the way. Then I put it in neutral and let out the clutch and I hear a little clunk. So I was thinking maybe it can be something wrong with my clutch/pressure plate. Or my transmission. |

Have you checked the torque on the 4 bolts for the rear bearing retainer plate? _________________ Rick

Is that behind the throw out bearing? |

No it holds the wheel bearing in. The trans. clunk sounds more like motor crank end play being too great. You need a dial indicator and push and pull on the flywheel to measure it. To adjust it you will need to remove the flywheel as there are 3 shims that you change thickness on one of them. This is where the Torque Meister comes in handy. P.S. make sure you use 3 shims if this is the problem. The only time you would hear this clunk like you say is taking off.

What mm of thickness would I need to get? |

You have to measure the end play 1st and see if you are in tolerance, then change the one that gets you there. I don't have the book in front of me but 002"-005" is good (you can convert to mm) if you don't understand SAE. |

I haven't took the motor out yet but i wanted to say that, when i took the motor out of my car before to change the transmission mounts there was what looked like dried up oil all around the inside walls of the bell housing. is that normal? and also when i was putting my car away i noticed that when i have it in neutral and i push in the clutch, it sounds like the motor idles a little bit faster and when i let out the clutch it idles a little bit slower. not a huge difference or is it noticeable when driving but i was parked by a wall when i was messing with the clutch and listening to the motor. Thanks in advance.

Sounds like the input shaft seal and bearing are shot. When the clutch is out , trans. in neutral, motor at idle, do you hear a "grumbling" sound coming from gearshift tunnel compared to when you put the clutch in? That's the input shaft bearing and maybe more, as oil in bell housing says seal gone and maybe input shaft is bent and wobbling because someone let the motor hang on it trying to get it in or out of the car. And idle faster with clutch in is normal as it's not turning the trans. gears. |

Well when it is in neutral I do hear some kind of rattle. It's not too loud but noticeable if you listen closely. Then when I put it in gear that sound goes away. |
