I did post this video in the DIY section, but I thought it has a better chance of saving money for anyone who has a ruptured / blown diff bushing if posted in the general section.

Love and appreciate all of your videos.

Would you suggest doing something like this as a preventative measure before any rupture happens?

Infin88: Thanks for your kind words about our videos!

If you bushing has not ruptured, I wouldn't do anything. After all it is still working as designed. BUT if you notice drip marks on your subframe or exhaust, this is a quick and easy fix.

Great idea! I believe this is what you used.


Wonder if there's a 3m or permatex equivalent.

Very clever and practical, and truly excellent under-the-car video. You certainly deserve compliments for this one, OP.

I said this in the DIY thread, and say it here too... I think you should go ahead and replace the two side bushings, since they're a relatively easy swap, and you already have them. I believe it was 4DRZ who did the side bushings months before the main one, and was surprised to notice the changes just from those alone. The theory is that the main bushing is holding the weight with vertical compression, but the side bushings actually take more abuse as the drivetrain twists. Right, wrong... IDK. But putting the idea out there anyway.

Go back to your video and watch the right side bushing movement.


What, intentionally cut the bushing? Yikes!

The best thing you can do prevantatively is swap the bushing before it ruptures. I had that done while the diff was down for a gear swap to a shorter 4.083 final drive, more for peace of mind than because it was needed. And honestly, I wasn't sensitive to any change afterwards with the poly mounts. But my OEM mounts were fine and only had 35k miles on them, so I guess that makes sense.

Try not to worry too much about this happening. There's no urgency or emergency if it does. It's not a safety issue. Lego went a whole year with his main diff bushing blown.

Nice fix. This is a pretty common approach. Way back in the 90s when I had a Neon R/T, this was the technique used to fix the front motor mount.

Good work. This will undoubtedly save someone some $$

That is exactly what I used.
Almost any kind of polyurethane could be used.

I chose to use 5-minute epoxy as it is easy to find and inexpensive.

gotta say its a great temp fix for those not wanting to mess around with the diff! cool tip

If that epoxy holds up, it might be more than a temp fix. We'll revisit in a year

You could even buy some syringes on ebay and load the epoxy into it

This epoxy also comes with an applicator

Wow, really cool; thank you. I had resigned myself to having a blown bushing (I haven't checked, but my car has 100K miles so surely it is blown), but this would be a super easy fix to do along with my sway bar bushing replacement.
