Question Clutch Replacement (Luk or Centerforce)

Hey All.

Been looking into replacing the Clutch in my TJ. Currently it runs fine don't really have any slippage when I'm doing day to day driving. Only 57,000 miles.

The Throw Bearing is really noisy so it definitely needs some grease or replacement. Figured if I was down there performing that work might as well look into changing out the clutch as well. I have smoked it out a couple times in the dunes.


In any case of the forums I have read everyone has been recommending Luk clutches. I have a buddy that has a centerforce 2 in his 69 Bronco and swears by it. Anybody have a great result from putting a centerforce in compared to a Luk or am I just wasting money?

I go off-roading about once a month but am hoping to get into it a little more and more as I do some upgrades over the next few months.

Painting the undercarriage with Por 15 (for rust which bothers the hell out of me) and replacing parts as I go from front to back.


Any Help?

Thanks.

Just go for the luk. They are known to last well past 100k even with offroading and arent too expensive.

Thanks! I did a whole lotta research between the two and sounds like Luk is the way to go. While centerforce would also be a good option Luk is an equally suitable clutch for a cheaper price.

I would not go with a Centerforce at all. They are double the cost of a Luk without any benefit over a Luk where a Wrangler is concerned.

How many miles are on your existing clutch and exactly what noise are you hearing that makes you believe your throwout bearing is going bad.

Does that noise you're worried about happen when the clutch pedal is up when the engine is idling & the transmission is in Neutral or does the noise happen with the clutch pedal down when you're stepping on it?

Some people say change tranny fluid and add Royal Purple Synchromax fluid and the noise will stop.

Mine makes noise with the clutch pedal up and in neutral, I always thought that was my pilot bearing and no big deal, am I wrong?

Jerry:
I have the original stock clutch with 58000 [just turned over today ] The noise happens when I am depressing the clutch, with a click when the clutch is almost all the way depressed. The best way to describe it is in the following link.

(Link doesn't have the click noise)

Only mine is worse. Some people tell me its the plastic end cap on the slave cylinder shaft that pushes up on the fork but I have also read it could be worn clutch fingers or even the throw bearing.

Either way it is getting worse and worse and I want to do something about it.

Trendsetter:
Flushed the tranny fluid about 6 months ago and still had the same problem. Didn't use Royal Purple though. Got the MOPAR stuff.

Reno:
I don't know. Haven't researched that issue before.

Thanks all.

I have had my LUK clutch smoking during some rock crawls at Rausch Creek. Still shifts and grabs great.If I ever needed to replace again I would use LUK again.

I have honestly just been going with the advanced auto factory replacement clutches(perfection) in my S10s and Jeeps.

I havent been let down yet and I get a discount from there. I dont see the added advantages the "performance" clutches offer being any benefit to us. Id just focus on getting a name brand that your comfortable with and has a good rep among trusted people. In this case Luk seems to have the blessing of some trusted forum members, thats where Id be heading.

If a transmission is noisy & refilling it with fresh appropriate lubricant makes it quiet, I would expect that transmission is about due for an overhaul.

That noise is normal & is just the sound of the bearings being spun by the input shaft from the engine.

Could be the throwout bearing, pressure plate, clutch fork mechanism, or all of them... you'll just have to get it apart to know for sure. Luk's or Sach's clutch kit would work fine. I'm a Luk clutch fan myself after smoking it many times without causing it to fail prematurely.

Parts Geek has Luk's for the 4.0L for about $93, and for the 2.5L for about $75. I believe shipping is around $8.
