Drive shaft?
 
So i just put on a rear sway bar and now i'm pretty sure that its causing my U-joint to wiggle every time i get out of first? does anybody know if they make a kit that can fix this or if this is even what the problem may be?

MR.CLIFFORD 04-17-2008 05:29 PM

How does a U-Joint "wiggle"??

Can you explain better what is going on?

4Jeepn 04-17-2008 08:51 PM

Rear sway bar.. you replaced the stock one.. or didn't have one at all and put one on... FWIW.. I don't even have a rear sway bar on mine.

agreed. I don't run a rear sway bar either. :flipoff:

Its only in first gear. As soon as i start out of it it seems like it might stall. Kinda like when you start in 2nd and have to give more gas. It causes my entire frame to shake a bit. Feels like something is loose and is not catching all the way.

MR.CLIFFORD 04-18-2008 03:16 PM

what size tires do you have?

1BLKJP 04-18-2008 04:41 PM

Can you grab your driveshaft and make it move in any direction other than a hair bit of rotation? Probably a ujoint just getting old and wearing out. 12.50 and about 20 minutes and you'll be back in business.

Does it knock too? There will be "heavy" knocking from the gears but does the U joint knock?

JimmytheJeep 04-21-2008 03:38 PM

I have 33x12.50 now. It doesn't make a knocking sound, just doesn't seem to catch. I'm leaning towards it being the u joint.
Thanks

Has anyone jacked around with the pinion angle? If so, that symptom points to it being too high.

That said, I'll also say that removing the rear antiswaybar on a TJ just degrades its performance offroad. On-road too, but those who remove it seem to think removing it helps the rear axle articulate better... it doesn't. At least not in a usable manner. :)

why is it you listen now and not the 100,000 other times everyone else told you?

because many people explain it like this when one asks or did we forget?

when teaching falls on deaf ears you tend to quit helping.

Triple88a 04-21-2008 08:20 PM

oh i see.

Its quite nice when one gives a reason why they say something...

to back your statement up

Yeah, really.

The rear antiswaybar helps keep the body and frame under control on extra steep or very off-camber terrain, which could mean the difference in rolling or tipping or not.

Removing the rear antiswaybar does not increase usable axle articulation. The slight amount of additional movement it would gain comes at a price, that there is then no downforce on the tire with the least traction, which the antiswaybar helps provide.

For those and other reasons, those who are doing the very toughest trails in their TJs most often have their rear antiswaybars in place and connected. And if you haven't heard this from me before, I'll just say that John Currie WON the US national rock crawling championships in his FireAnt TJ that had front AND rear antiswaybars connected.

Both of the below are photos I took of John Currie in Johnson Valley in the final event where he won the overall championship. The first photo is of his Fire Ant TJ. The second shows his Fire Ant's rear Antirock antiswaybar which is essentially the same stiffness antiswaybar that comes in a stock TJ. His entire frame & suspension was custom made so he had to install his own antiswaybars (front and rear). If they didn't help, he wouldn't have them installed front and rear.

Plus if you have a rear antiswaybar plus an Antirock up front, it helps the front and rear suspensions work together instead of fighting each other as they do when one is disco'd and the other isn't. The front and rear suspensions are better balanced then so it all works together much better. :)

I added one more final note to the above...

Triple88a 04-21-2008 08:38 PM

the one fighting the other if one is discoed and other isnt?

so what you're saying is its better to have both connected than both disconnected?

Yes, it's never good to have both disconnected.

Triple88a 04-21-2008 08:53 PM

so discos are in fact a bad upgrade according to that theory?

That's why something like the Currie Anti-Rock comes into play.

but then whats the point of people making statements if they cant back them up? Thats why ask questions. Many times i'm curious so just because i'm asking a question doesn't mean i'm against it or something.

also as the currie goes.. whats the difference between the stock one and the currie? As far as i know the currie has multiple holes that make it "softer" or harder" but is that it?

Who said we can't "back them up"? Once in a while these kinds of things get so drawn out that we (at least me) get a little tired of re-stating the same things over and over again over the years. :)

JimmytheJeep 04-22-2008 02:02 PM

does anybody know if you can buy a replacement drive train that is one piece? the one now moves a bit and has two separate pieces to it. I'm looking to get a new one that is just a solid piece.
