Hey everyone new to the forum. I have a 99 Jeep Wrangler TJ 4.0 4x4. When I pull off in first gear really bad shutter. Cant seem to figure out why? Replaced a few parts so far and still no such luck. Any help would be amazing

 

[gregtp09]

Also to note
- 4 inch lift Currie springs
- Currie adjustable control arms (uppers and lowers) (front and rear)
- new sye kit
- engine mount lift
- new low pro mount
- adjustable track bar (front and rear)
- black magic brakes (front and rear)
- Novak transfer case shifter
- 33 12.5 15 tires
- luk clutch and flywheel

(Shutter was happening before all these parts were installed)

Have you replaced your transmission mount.

 

[gregtp09]

Yes I sure did. Replaced stock mount with the lo pro mount from undercover fab works

 

[wadewolf]

Does it do it in 4lo?

 

[gregtp09]

Does not do it in 4 low. Only does it in 2wd and 4 high

Clutch chatter maybe? How was the flywheel? "How are the engine mounts? Is the rear main seal leaking or has it started to leak?

A worn out clutch shutters when taking off in first gear.

 

[gregtp09]

Just installed new flywheel, clutch and throw out bearing. Motor mounts are new 1 inch brown dog mount lift. Transmission mount is new lo pro mount. It has small leak but cleaned it up on clutch replace and made no difference

Pressure plate bolt toque

 

[gregtp09]

About 27 lbs for the pressure plate

 

[gregtp09]

Some specs said 25 and others said 30 so I went in between

 

[Digger84]

Sure sounds like clutch chatter

Not uncommon which is why on most vehicles people resurface flywheel when doing clutch as one time having to repull tranny is enough to never want a repeat

I know dome on TJ flywheel so Emory cloth only

 

[Digger84]

With new pressure plate disc or flywheel souls not chatter unless bad parts or contamination

 

[gregtp09]

That's why I'm so lost on this. Because it was doing it before and flywheel had little scorching but other than that looked fine. Then new one and still same problem so can't think of anything else. Unless it's some inside problem somehow

 

[scorro]

Crankshaft pilot bearing possibly?

 

[gregtp09]

Guess I got to take it all back apart and replace it. Anyway to check it without removing trans??

Did you ever figure out what the problem was? I am having the same exact problem as you, vibration in 4x4 high and 2wd but not low I have replaced a lot and checked a lot of parts. And still have the vibration
