Thumbs up VW BALL JOINT FRONT AXLE STRENGTH ??????

I have a VW body I'm cutting to use as an old school hot rod project . I plan to cut it as a track roadster body and power from a 230 CI Chevy 6 cylinder .

My question is : Will the VW balljoint front axle assembly carry the weight of the Chevy engine ? If it will , it will save me loads of experimentation working out bump steer etc on an strait beam type axle .

Thx Gonzo

Default Re: VW BALL JOINT FRONT AXLE STRENGTH ??????

the issue is going to be
1) are you puttingn the -6 on top of the axle
OR
2)are you pushing the axle forward in front of the engine so the engine can sit lower,behind the axle.
a -6 is pretty long so you will have to push that axle pretty far forward
a VW beam axle is pretty high ...if you put the motor on top of it is going to be really high...remembern the chev-6 wants to be level so if you put the emgione on top of the beam the whole motor& tranny will have to sit up there.
SO
if you put the axle waay forward & mount the engine behind it I say the beam will handle the weight. If you put the engine up on top of the beam it will not.
BTW sounds like a great project.. start a thread & post lotsa' pics!!!
P.S. remember, to mount the engine behind the beam front end you will have to eleminate the framehead & entire tunnel. essentially fabricate an entire frame

As far as it being strong enough, I don't see a problem. these beams stand up to a tremendous amount of abuse in off road racing. The further out your mounting points are toward the shock towers the stronger it will be. The beam in the photo is 6" wider than stock, this car was constructed in a garage by a couple of rookies with a tube bender and welder. We never did bend the beam but shredded up other components of the suspension.
The stock torsion leaves IMO will not hold up the weight of the chevy 6 cyl. sway-away makes higher rate leaves that would work or a coil over shock would also be an option!

show us some photos!

i recently saw a v8 bug with a stock beam mounted just in front of the crank pulley, and it seemed to be holding up just fine after 30+ years...

...though i don't know if i'd want to drive it.

Thumbs up Re: VW BALL JOINT FRONT AXLE STRENGTH ??????

The front axle is the only VW compnent involved other han the body . The freame will be fabricated from square steel tubing with the engine and radiator behind set back behind .

I realize this is Volksrod site, but the VW beam hanging out in the open in front is just not a real nice appearance. Especially vs a simple dropped I-beam axle.

Is the VW beam strong enough? Yes, as proven by off-roading and all the VWs running around after all these years and miles.

Another issue for consideration is the bolt pattern of the VW front vs the (I presume) rear differentail from some RWD vehicle.
