Pls help diagnose...

Post by nige1171 » Sun Sep 27, 2015 12:49 pm

Pulling away slowly and suddenly a very nasty grinding/ vibration and loss of drive/ gears.

Back on my drive I jacked up the rear to wiggle the wheels (to pretend to myself I could identify something that way) only to find the driver side hub loose. Not loose at the hub nut it would appear, as the cotter pin is still there but movement of the hub on the driveshaft?

There is a lot of brake dust and with the wheel off the ground and in neutral I can turn the hub nut with my fingers!!??

I have a video on my phone but the forum says a .mov file is invalid when I try to upload

What's happened and what could be the cause of this?

Any help appreciated...

You may have stripped the splines. Just a guess, but someone with more knowledge in this area may chime in soon.

My rear drums are split items with the snout machined down to fit on the beetle s/a gearbox. Are these readily available off the shelf if that's what has failed?

Sure sounds like stripped splines on the drum, not sure how readily available 'modified drums' are, maybe try someone like Type 2 Detectives??

Hi Nige,

I'm no expert mate, but it does sound like stripped splines - perhaps machining down the spout has taken away some of the spline mating surface which may not have helped.

I remember that they did a beetle on that car program with Leepoo & Bernie and put a scooby engine in it - pulled off & stripped the splines in the rear - may be worth taking a look at youtube to see if you can find the program. Also seem to remember that the same thing happened to an early beetle that Drew Pritchard bought off T2D on Salvage Hunters. Pulled off - loss of drive - stripped splines.

When using Beetle hubs it happens on a regular basis as after market hubs are sh!te ! Always use a new hub nut too. Copper slip the threads and make sure it's torqued up correctly. GSF are supplying Brembo Beetle hubs at the mo and I've never had a problem with them but not sure if doing bus hubs but Creative Engineering might do them...?
