- Hmmm, d00d. Didn't know it was broke. Worked fine when I checked it after posting. Ghost in the machine maybe? What did you do with the extra /'s you took?:laugh_ti:
- No argument that it's easier. I'm only interested in "easier" if it results in an equal or improved outcome. I figured the ridges were there for a reason. With more than 7,000 posts here, you likely know many things about these cars that I need to learn. Do you think shaving the ridges would result in an installation equal to or improved compared to leaving them intact? I did think about shaving them, I'll share my reasoning for not doing so.
I read a few posts about peoiple finding water entrapped within the original bushing assemblies. As I looked at these new mated-pairs I noticed design features that seem intended at directing water to the exterior. First, the top steel cap. On these bushings it wraps well down the side of the flex material compared to the o.e.m. It appeared designed to deflect water away from the steel/rubber mating plane.
Second, the same top cap includes an ovate cone-shaped section that protrudes well into the interior of the lower half of the bushing assembly, and actually serves as a funnel for any water migrating between the cap and the car body. The bolt extends through this "funnel". The bottom of the funnel is shaped to allow any diverted water to shed into the bottom bushing-half, rather than be trapped around the bolt.
The bottom bushing-half is formed to divert this water to two drainage holes that vent to daylight. The drainage holes are positioned to prevent any retention of fluid in the bottom bushing-half.
I was curious enough about this design to assemble the two halves, cover the bottom bolt hole with my finger and pour water into the "funnel". It drained completely. Seemed like an immense improvement over the original design.
Next - the hard plastic shell around the bottom bushing-half. The part that contains the ridges. This plastic shell will act as flashing/fairing to prevent any water from migrating between and bottom bushing and the bottom surface of the subframe. As a contiguous surface, it would re-direct any of this water back out to daylight. If I were to compromise this plastic shell, water could migrate between the plastic and the interior material, defeating what I assumed to be a part of the design.
Finally, I assumed the ridges were intended to resist the tendency of the bottom half to rotate as the bolt is torqued. Any rotation of the bottom half would compromise the alignment of the ovate steel funnel (male ) with its much softer molded rubber mate (female).
Anyway, many words to help you understand my thinking. It took a whole lot more time to type this than to clearance the subframe for two bushings. I'm interested in any response you care to share.

It took me 5 minutes with a little round hand file on the subframe , it's alot easier than it sounds. And everything fits like a glove.
