+--- Thread: Double front shock absorber (/showthread.php?tid=3291)
RE: Double front shock absorber - Dave Wortley - 13-09-2019
If twisting the axle doesn't work for you another method is a horseshoe shaped washer 5mm thick between axle and rad arm. I did this on my chummy as a temporary solution to wandering. Was still there 25 years later.

I agree - the kingpin tilt is critical to stop wandering !
Just a tad back from vertical works wonders

Dave - do you have any pictures of the "extra-arm" modification? When younger "wander" didn't seem to bother us - but then, we were rather less fearful...

Tony if you take a look at my special build thread I showed one way of doing this recently

Rick,
quite a number of the cars I’ve worked on have had the radius arms fitted incorrectly, once they are swapped to the correct side self steering disappears. May be worth a look...
RE: Double front shock absorber - Rick F - 14-09-2019
Thanks Ruairidh - just remind me again, what is the "correct" way round?
RE: Double front shock absorber - Ruairidh Dunford - 14-09-2019
I cannot remember the 1a casting numbers (these are not always clear anyway to be honest) and am not near a car to check. The thick end of the wedge must be at the bottom on both sides when fitted correctly. Post a photo of what you have if you are not sure. Some have come in with two o/s arms fitted...

Thanks Ruairidh - I'll check asap. Currently getting ready for a 10-day holiday in Portugal ( sans cars)

Based on all the good advice above, I carried out the following:
New shock absorber discs, springs, bushes etc.
“Panhard” mod to nearside S/A arm - the sideways movement of the axle has been “absorbed” by the spring shackles, which, with the wheels on the ground, are now at very different angles.
New radius arm ball joints.
Slackness taken up in the steering box.
Tyre pressure reduced to 22psi all round.
Hoppity-skippety steering seems totally eliminated and the ride is much stiffer all round – may ease off as disc bed in.
Only downside is steering wheel spoke is no longer at 12-o-clock when driving straight ahead. I prefer it that way, so may realign it when I’ve nothing better to do! In the meantime, thank you all for your suggestions and advice.
RE: Double front shock absorber - Zetomagneto - 05-10-2019
The spring shackles need to be at an equal angle side to side, it sounds as though you need to adjust the length of your improvised panhard rod.Or you could use a fixed shackle at one end of the spring and put the shock absorber link back on. If using the shock link as a panhard you need to weld an “eye” onto the end of the link to accommodate a rubber bush so involves a bit of work either way
