Take a look at your heat shield covering the cat. Could be the source of the rattle. Gear box oil could have been spilled before and the ride made it shift and start dripping? See if the fill cap is tight.Went on it's first ride. Now I'm tearing my hair out looking for the loose metal making the vibration/rattle the shop can't reproduce. Oh, and freaking out about the skid plate covered in gear oil dripping everywhere after 35 miles.........
This was built so bad it hurts.
Also take a gander at the Exh tip. I've personally had this happen, and read it here a few times as well. Some just loosen up,,, mine (and others) actually cracked at the mounting ring.Take a look at your heat shield covering the cat.
Yeah, going to be drilling those out soon. What a crap design choice there........Take a look at your heat shield covering the cat. Could be the source of the rattle. Gear box oil could have been spilled before and the ride made it shift and start dripping? See if the fill cap is tight.
Best thing to do is drill out the rivets on the rear skid, and replace with rivnuts. Plenty of threads on it in here. Drop the rear skid, and it makes oil and rear diff fluid changes a walk in the park.
That's exactly what mine sounded like.... swore it was the heat shields. Did the same thing you did, MANY times. Didn't happen until the car got warmed up,,, and the hotter the car got, the worse the rattle was. If I revved the engine the rattle would go away until the RPM's came back down. Finally grabbed the exhaust tip while it was idling and the rattle stopped. Discovered the mounting ring was broken. Who'da thunk it?The weird thing about the noise is it's very obviously a heat shield/sheet metal noise. Only happens when hot and driving over rocky terrain. If I stop and smack the shields there's no movement or noise.
It's super irritating though
I do have a slight rattle at idle that sounds like what you're describing as well when hot and only when hot. I'll check it out.That's exactly what mine sounded like.... swore it was the heat shields. Did the same thing you did, MANY times.

Later found out it's not uncommon.
Not saying that's what yours is, but it is something to keep in mind in case you get a mystery rattle at a later date.
Nice! Skills!Started fabricating a new dash but got held up waiting on material so installed a new radiator and put together a crankcase breather and installed it.

With the skills you have, why would you? LOL!Thanks for the complements. Drag racing was shutdown again at the beginning of the year and my drag car has been parked for two-years now so I bought an X3 to play with. Then I got to thinking, why not build it into a desert racer. I just can't leave well enough alone.
I thought everbody knew 10 years ago that without pics it didn't happen.32” System 3 XTR370’s showed up today. I set them next to the buggy. They look pretty good. Still waiting on the Alba Racing wheels. Hopefully it won’t be too much longer.
Where did you buy the UHMW?Recently I had installed some SATV boxed high clearance arms. Wanted a-arms guards like my factory arms had, so I cut/bent up some UHMW to make my own. Material was <$100.
Is that a super ATV or the halo locker
