--Just returned from having my front end aligned.  I located a wonderful, experienced guy right here in Hot Springs who knows his stuff---a rarity these days!  I took my specs with me thinking he would need them but he already had them.

 

The specs call for minus 1/2 degree negative camber on the front tires and 1/8" toe in each side.

The alignment guy pointed something out that makes a lot of sense and I wanted to pass it on.

The specs we both had were published back in the days of bias ply tires--not steel-belted radials

and the specs should be modified to compensate for that!  So instead of toe in of 1/8" per side he went with 1/32 per side for a total toe in of 1/8".  Also the camber in the old specs called for 1/2 degree

negative camber for each front wheel and he used -.4 rather than -.5 degrees. 

 

I was happy to find someone who knew VW bug alignment and this 51 tear old guy has done a lot of these.  My Speedster drives better than ever and it was already super smooth.  The thing that told me my alignment was off was that I heard a tire squeal when I backed the car out of the garage.  The floor is pretty slick and the tires were "scrubbing" to make that squeal.  Before the alignment, the toe in was; Left front tire, + 1/4"  and the right front tire was -1/8".  So much for my DIY approach using the Muir book!!  I'll do a lot of things to my car but I'll let this pro handle alignment in the future.  $60 for an alignment is a lot cheaper than new tires!  It might not matter with the cars that put just 1,200 miles on in 3-4 years but it matters a lot for those 2,000 mile jaunts some of us enjoy.

 

I hope this is helpful to you folks with pan based cars.

They all pull a bit right because of road crown. On many cars this is compensated for with caster--a bit more on the outside (right) side. With VW beams the caster has to be equal all across, so you end up with just a little drift.

 

My reading of the toe was 1/8 in on the front and 1/8 out on the back for IRS cars, give or take 1/16th, and that should work. Camber on the originals was 0 or a little positive. That looked insane to me so I specced mine at .5 degree negative. It really does seem to make it better.

Yes indeed. Or, even more important, not squirming all over the road. My car's suspension took a bit of tweaking just to make is reasonably acceptable, and new tires were just one small part of it. I was lucky, too, to stumble into an alignment shop (Atlantic Tire in Baltimore) whose people were willing to listen and think about the car they were working on, instead of just reading the book. (There is no book for the BCW Model 52 and, anyway, the build instructions made for a really hard riding and bad-handling car).

 

Only thing the alignment guys did wrong was pump up all the tires to like 34 lbs. That made the ride home less than awesome but was easily fixed.

Yes, those specs are for VW bugs 1960-1968.

 

Be aware of the fact that those specs were for bias ply tires---not today's modern steel belted radials. 

 

Find a  shop that knows how to align the 60's bugs.  I had a bad experience with a young mechanic who had no idea about what you adjust to bring the front end in alignment.  The last guy a couple of weeks ago was terriffic and has done a LOT of these front ends. 

 

Good luck with it!

Sure could use some advice on this one.  I had my pan based towed because I got stranded after a gas hose fiasco (had a kink)

 

Now suddenly my car steering wobbles horribly when I accelerate past 55 or so.

 

Could the alignment be out of whack?  Could a tow hooked up in the wrong location cause a bent axle or something?  I got the car as a hobby so I want to do the work myself if possible (not alignment)  I changed out the steering damper which seemed to help a little.  The car is a VS build.

Good on ya' for doing work yourself.  In this instance, however, unless you have alignment experience, you really need to take it to a good alignment shop near you, explain the symptoms, and have them fix it.  You really don't want a dangerous steering wobble at highway speed.  That's how bad accidents occur.  Good luck and let others know what you find.
