Re: REAR suspension un even
Thanks Lee ,I'll look into this. I don't think it is on the twist as the door gaps and the way close would be affected too surely . The gaps on this bug are all equal .

Re: REAR suspension un even
I posted it only as another thing to think about; I was warned about checking the pan myself by someone who was in the business and by a couple of discover the problem). My black buggy pan was out of a Baja and it was badly rusted in the floors and a couple of other places in the body so it was also questionable to how it looked hence the advice I got. I did find and fix a problem or two that way.GARRICK.CLARK1 wrote: ↑Sun Feb 23, 2020 3:12 am Thanks Lee ,I'll look into this.

And yes, I do have a small twist to the front beam but not enough, for where I ride, to make that much of a difference. I have to check but I think the blue buggy might have a small twist to the frame head also.

Re: REAR suspension un even
Does anyone bother when they pull rear torsion bars out of there original position.
What I mean is ... BUGS/GHIAS have had the torsion bars fitted for years and have been twisting for years in this position, so if you remove the bars from the car ,you loose the position that they were once fitted ,so re fitting them to a VW you can have the bars fitted and they will be stiffer because they've not been run in the new position ,which makes getting both sides an equal ride height more difficult.

I made this string a long time ago and things have changed somewhat but not so much the basics of it. The chain thing was because I was using a glass buggy and the weight of a stock Bug wasn't there. But the basics are still good but Photobucket messed up the pictures some because I wouldn't pay ransom.

This is false. It doesn't matter how you install the bar, it's spring rate is exactly the same.GARRICK.CLARK1 wrote: ↑Sat May 09, 2020 9:03 am ... ,you loose the position that they were once fitted ,so re fitting them to a VW you can have the bars fitted and they will be stiffer ...

Re: REAR suspension un even
While true in theory, on trucks at least, you get a non-torsional weakening of torsion bars as they sit slightly bent upwards from bushing failure. Ultimately though, get the car perfectly even by just getting some adjustable spring platesBruce2 wrote: ↑Sun May 10, 2020 4:09 amThis is false.

Re: REAR suspension un even
After resetting the rear torsion bars many times I did discover some things. Stock torsion setting runs in the 19° tp 20° range, I have reset the stock torsion bars as high as 30° but then the suspension seems to largely go away; IOW it gets crazy stiff and scared me. It was more of a feeling I got when driving around on the uneven dunes that got me to back off on the preloading.
I found (my opinion) that the top end of the reset should max out somewhere in the 24° to 26° range. After that newer stronger bars should be looked into. I have also been told that torsion bars take a "set" (hence the marking of RH or LH on the ends of the bars) and then can be more capable of failing.

Re: REAR suspension un even
Ok. SO if I start again, strip down both spring plates and fit them at an equal degree , lift them onto the stops ,bolt it all back together, the rear of my bug should be equal height both sides.
Hope so .
I do have a level floor in the work shop.
I'll over kill measure it. Its been 1/2" lower on 1 side for too long.

Re: REAR suspension un even
Dont bother making sure the pan is level. Just get the angle of the main tunnel and use that as your reference frame

" … or you will have to do some math to correct the angles." That is what I was referring to. I think the tunnel and the sides of the pan are/should be in alignment.eskamobob1 wrote: ↑Sun May 10, 2020 3:34 pm Dont bother making sure the pan is level.

Honestly though, a digita angel finder you can zero on the tunnel is like $20. Its such a useful tool too

Your not brain dead; what I wrote probably wasn't clear as I was in a hurry as I was in the middle of something else I was doing here at home.eskamobob1 wrote: ↑Sun May 10, 2020 8:07 pmLol.

The digital angle finder that is shown in the picture is so handy... most of the time anyway; I also use bubble gauges and other similar tools for setup and some do help on angles also. If you measure the angle the pan or tunnel that is not perpendicular then you have to add or subtract (the math part) that angle from the angle you are measuring in order to come up with where you are.
Whether I am using jack stands or my rotisserie I try to set things up parallel to the floor before I get too detailed in what I am trying to do. Just part of the ritual and it makes things easier after the proper setup work is done .

Re: REAR suspension un even
Your average smartphone has a digital level built in.
I’d suggest getting the pan level side to side, to avoid any complication. I’d also level front-to-back (but that’s me )or at least close, then zero the level using the flat area of the tunnel that VW provided.
Also lift the spring plate by hand to take up the backlash in the splines, when measuring.

Re: REAR suspension un even
I've down loaded a clinometer off google play. Its digital down to 0.1 degree ,so as long as I'm equal both sides at 26 degrees I should be good, I'll level the car front to back, left to right
Thanks for the good advice
