My neighbor’s daughter’s 2007 wrangler throwout bearing came apart last weekend at around 80,000 miles. It makes a nice metal against metal grinding noise when you press the clutch pedal, and you can see the ball bearings from the throwout bearing laying in the vent at the bottom of the bell housing.
Lee Parks made a good video showing the failure on his 2007 with pictures and info on a clutch changeout after his throwout bearing suffered the same fate.
I am tearing apart the 2007 jeep in my garage at the moment, and the only things I have to add to Lee’s video so far:
1. Use a prybar against the white plastic bushing on the transfer case linkage to prevent breaking it. If you pry on the black cable end, you’ll likely break the white plastic bushing.
2. You can get a 15mm or 16mm open end wrench on the passenger side square nuts holding the y-pipe to the header from below. Use an electric impact with a knuckle and extension at the same time on the 15mm bolt head.
The cages on all four square nuts holding the y-pipe to the headers were disintegrated on the 2007 I’m working on. On the driver’s side you can reach the square nuts easily by opening the hood. The battery box and heat shield get in the way on the passenger side.
