Yes, bulkheads can bend in crashes. All cars are at risk for that. Easiest thing would be to take off the bulkhead and check it on a flatboard to see if it is bent and wobbles when you tap on it.

Thanks Jeff, guess I'll see if I can shim it out before buying a new one. It has a slight wobble on a flat surface, so I guess it's bent. I checked the holes on the bottom, and they're equally drilled, so that pretty much rules out a manufacturing defect.

All the times my diff felt like that, the thrust bearing came out in several more pieces than when it went in. I replaced the thrust bearing with one that was properly lubed, and used the ceramic diff balls, and the diffs have been great ever since, which is about 4 months now. I haven't tried ceramic thrust bearings yet, but I may do so down the road when I need to replace the current ones.

Check the thrust bearings and make sure they are packed with black grease. But before you remove anything on that diff hub, check to make sure the "snap ring" is fully into the groove. I know this is sometimes over looked and gives people some puzzling diff problems.

Yeah, shimming it for now should be fine as long as the diff or pulleys are not binded at all.

Well, I recommend running the diffs so they don't slip. Running a tighter front diff will act more like a spool and take away some steering. Basically which ever end is tighter has less traction due to less diff action.

Ive got another question ive had my RDX for one race meet and it just doesnt seem silent as the other cars all the cars sound the same in stock group B but in A they sound real smooth, i dont think its the bearings because off the motor its really smooth. Ive got a monster stock if that helps, should i get a titanuim pinoin?

Motor could just be out of balance and making the noise. My car is dead silent, it's really cool lol.

You cant really. I guess you could send it to a tuner where they balance motors, and they can recheck it for you. Sometimes motors can come out of balance just by cutting the comm, or dropping the motor (oops!), or even just a really hard impact. It's weird...........

What's the right combination of spacers and hexes to get the front of the car to 190MM when using foams? Is it three 1 degree spacers under each coupler and the regular hexes?

Also, I was experimenting with the front sway bar, and I noticed that it obstructs the action of the suspension if the wheels are turned past about the half-way point. Is this normal, or have I done something wrong? I used the shorter bar for the front.
