08 Wrangler manual - ticking rattle

Hi guys,

I've noticed I've got a 'tick/rattle' sound in my manual. It happens only when in 2nd, 4th and 6th, but is most pronounced when in 4th.

The vehicle has travelled 102 000kms (which is about 63 000 miles on the silly scale). The sound is only there when the accelerator is pressed. If left in 4th there is eventually a smell like wiring overheating.

Was wondering if anyone has heard of this problem before, and if so, what the possible causes are. Am I going to have to replace a clutch or could it be something minor?

Any suggestions would be appreciated

Thanks

I have that same sound but no burn smell. Never have been able to figure it out.

Hi Col sorry for the late reply.

Thanks, I gathered that a few people have had the problem before.

Anyone else out there got any advice? Just so if in future someone comes looking and finds a thread with not much help (we've all been there)

Sounds like it's the famous driver side exhaust manifold crack. My 08 did the exact thing at about 40k on it. Easy to fix pull the heat shield off manifold and you will be able to see the crack very easy. Let us know what you find.

its more of a rattle from the transmission. Mine I can sometimes feel it in the shifter. Ive seen manifold cracks before and they were different.

Thanks Walt I will look into that, but as Col said, it's definitely a transmission thing. As I mentioned, it only happens in 2nd, 4th and 6th. I'm not mechanically minded, so hoping that might be a clue to someone more savvy than I am.
