Quick question about an issue

My 2.5l yj shakes and squeaks a lot when pulling off a dead stop. I assumed that the clutch is slipping in some way. Does this sound accurate? If not what is causing the problem? It's a real PITA.

Normally a clutch won't start slipping in 1st gear as that is when has the best lockup, normally you'll notice it in say 3rd gear when you floor the gas and see the rpm's increase without the speed increasing, or going up a hill in a higher gear and hearing the engine rev with no increase in speed. Have you checked your clutch fluid? Has the jeep sat for a long time? I guess the pressure plate could be rusted and causing rough engagement.

No it has not sat for long, not a spec of rust on it. Just topped off the fluid the other day. The best way I can describe it is as if you are in 4 WD going around a shop turn and everything kinda squeaks and shakes if that makes sense.

Did you get the clutch hot by riding the pedal? that will cause the flywheel to become "glazed" and that in turn causes the clutch to slip.

Sounds like you need a new clutch and possibly a new or re-surfaced flywheel.

I never ride the clutch. I don't think PO ever put in a new clutch so there is a chance it's has the while 106k miles on it. What does re surfacing the fly wheel entail?

Taking the flywheel out and having the clutch side of it re-surfaced by putting it on a lathe and cutting it down much the same way that they machine front rotors for brakes.

Sometimes the heat cracks are too deep and you just need to replace it. If you choose that route, make sure you get the exact same flywheel. the 2.5L motors are balanced by the flywheel weights.

If you got 106K on the original clutch, then it has had a good easy life.

I don't have a lathe so it looks like I'll be purchasing one. Thanks for the help. I'll also get a new clutch and hopefully that will fix it.

I don't have a lathe either, but most machine shops can re-surface the flywheel for you. It's a common part to have done. Some NAPA stores also have the lathe in the back to do rotors, and they can do it as well.

If you take it off and it doesn't show any signs of heat cracks in it, you can do a home re-surfacing with 180-grit sand paper and an orbital sander. To just "clean it up". Make it all smooth and go until it all has the sanded finish. You want to be as even as possible with the sanding because like I said before, the 4cyl is balanced with the weight of the flywheel.

I use the orbital sander every time I do a clutch job. Usually with the flywheel still on the motor. Gives the new clutch a new surface to "bite" to once its installed.
