Rebel Racing Front Bushing - Torsion Bar Exposed
Recently installed RSR front bushing kit and there seems to be a gap between the bushing and crossmember wide enough to see the torsion bar.
Picture below, the entire front suspension is installed finger tight and both A arms move freely without binding. I've pushed the bushing as far back as it will go. This gap is a bit concerning for dust/water getting into the A-Arm tube plus I just want to make sure there is nothing major causing the issue. Any thoughts or is this totally fine?

Are you running the factory soft foam rubber seals that go there?

Good point and yes I installed those per the parts diagram shown as #20 below which are 2 gaskets placed in front of the the reverse lever (picture below).
I thought maybe there was a gasket located in between the gap but there is nothing referenced in the parts diagram. Assuming this is the proper way to install the bushing I may source gasket material and fill the gap. Just seems weird as the gap will no doubt let dust/water in.

May be different with a steel cross member. With my aluminum cross member the Rebel bushings sit flush. No gap

Anyone know if this is the case? No great reason to move to aluminum for the crossmember, but it's also not like it's a costly affair... |

After you have everything tight, you should be able to hammer, with a rubber sledge, the A arm front to back and have zero movement. If there is play, loosen the front bushing bolts slightly, and tap the bushing rearward, then retighten.
If the above checks ok, and you still have that gap, then it might be a steel cross member issue. |

So I pulled everything apart and checked the interior bushing housing, it looks like the factory welding methods create a slight protrusion preventing the bushing from sitting flush.
After many hours deep diving the forum I did find this problem has occurred for others on both the steel and aluminum crossmember and the recommendation is to add 2 torsion bar gaskets and place them in between each bushing and housing. Link to that thread below. I used that method and feel much better about keeping dust/water out of the A-Arm torsion tube. I may find some thin weather-stripping and place on the front side as a "belt and suspenders" approach.  Time to replace 30 year old suspension - little help please?
