|

I have some comparison pics of the BJ and 181 lower trailing arm and spindles.
http://forums.aussieveedubbers.com/viewtopic.php?tid=56811
You can see the difference in offset of the spindles from the ball joint centrelines.
You can see how the centres of the balljoints are the same for the BJ and 181 spindles
Standard ball joints, you can see the limited surface area that the lower ball joint(top one in this photo) has to work on.
BJ and 181 lower trailing arms
181 trailing arm has thicker wall thickness, upper BJ trailing arm has same thickness as lower 181 arms
BJ, modified BJ and 181 ball joint socket in lower trailing arm.
This shows the difference in the shock absorber mounts, but the axis and centre line of the shock absorber remain the same. The 181 stud is longer and the boss machined back closer to the ball joint to accommodate the longer sleeve on the 181 shocks. The 181 stud has a larger thread.
I can see no difference in the geometry of the 181 and standard ball joint trailing arms. I have easily modified a lower bj lower trailing arm to accept a 181 ball joint.

Ian use what you can, I've read some conflicting reports on the trailing arms and decided to make some comparisons. I got a 2nd hand set for my manx off another buggy owner(Apoligies to the purists). From what i've been able to work out the top trailing arm are directly interchangable and the lower with a minor modification. |

I just built an adjustable beam for my thing. I will be swapping to Ghia discs as well. Everything on the beam is stock Thing parts, including arms. I just installed ghia/bug balljoints into the thing arms, with the lower one flipped the right way. No problems at all. Should save anyone head aches if they are going this way as well. You can keep the beefier Thing arms. |

I would not swap the trailingarms from one side to the other... The end where the balljoints are fitted is in an angle and becomes totally wrong if you flip them...
Only correct way to fit Thing balljoint is to do as Mackaymanx did. I've done just the same now too.
Ready to be fitted into my -66 beetle.

Help me understand.
What did you do to the front end or are you just showing Type 1 vs Type 181 trailing arm differences? |
