Fast clicking noise after 4.5" lift...

Just finished my lift, now when driving I notice a nasty sounding click. I can get it to stop if I give it more gas, it also starts up just coasting with no gas. Sorry kind of a ****ty description, but anyone know what's going on? I'm still a jeep newbie... Also, this is in 2wd and I didn't notice this when I drove it before I had the alignment done this morning.

I got exactly the same thing at around 100km/h (60 mph), but goes away at 110 km/h...

When you lift your truck, you change the angles of your driving shafts which have not been designed to work at such high angles. What you hear is simply a little vibration and it is normal after a lift. It may settle after a while, but if you want to get rid of it, you will probably need a SYE (Slip Yoke Eleminator) and a new drive shaft...

What is scary is DW (death Wobble). This occurs while driving over little bumps on the road, the steering starts to rattle and shake like hell. The only way to stop this is to slow down...

To solve DW on my truck, I simply replaced the cheap Good Year Wranglers marked "economical" in their book to better tires. When I put these tires back on my truck, DW starts over again. This is not the case with my 31" Yokohamas or my 225 winter radials.

Does the clicking sound like its coming from the front, rear, or middle of the jeep? and Does the clicking speed up and slow down as the jeep's speed changes?

As best I can tell it sounds like a front end noise. And yes it does speed up/slow down depending on how fast I'm going.

Ok, I just drove it to work, have some more details.

Does it at any speed, in 4wd or 2wd, sometimes off and on, not constant, seems to get worse when I hit a bump.

I'm not the best at trouble shooting these kind of things so I'm not going to throw out any wild guesses But, here's what I would do based on that you just installed a lift and didn't have the clicking before I assume. I would take some time and crawl under there, make sure every nut and bolt is tightened down and there is no play in anything. Look at everything you touched or replaced including wheels. I'd also be looking at things like brake lines rubbing on the tires and such. Also I'd look at the front driveshaft - U-joints? Then if you didn't grease anything after the lift I would do that now.

Well I checked all the bolts, everything is tight, greased everything. Could a bad u-joint sound like this? It even makes this noise while braking sometimes.

Last try here...

If you've ever heard a CV joint going bad it sounds exactly the same as what I'm hearing on the jeep. It's not consistant, so I don't think it has anything to do with the drive shaft, but who knows. It's a very metal on metal rattle/click.

One way to tell for sure wether or not its your front driveshaft or U-joints is to completely remove it. Drive it around this way and see if you still have clicking sounds. If you do, you know its something else. If the clicks go away, reinstall the driveshaft and see if they reappear.

Good idea, I'll give that a try tomorrow. Could I do the same thing with the rear DS? put it in 4wd and basicly turn it into a front wheel drive?

Tecnically, Yes - but I don't see how that would help you diagnos the clicking in the front

Well it's hard to pinpoint a noise when you're driving with your haed sticking out the window, so I'm not positive it's a front end noise <img border="0" title="" alt="[Wink]" src="wink.gif" />

I pulled the front DS, noise is still there. Almost positive it's the rear drive shaft now.

Very well could be the rear driveshaft since you upped it 4.5" increasing the driveshaft angle. Still stock driveshaft I presume? If so, before you think about spending any money on the u-joints, now may be the perfect time to do a SYE and longer CV driveshaft if you need one.
