Grab a cold one, this one's long. :beer:


I'm pretty sure this doesn't go under Axle/Suspension/Tires unless drivetrain is suspension (which I didnt think.) Anyway,

Ive been trying to figure out what's going on with my front end. There has been a clicking sound coming from underneath the car for the past 3 weeks. I haven't been driving it. Only to and from a shop, but at low speeds. I at first thought it would have been the T-Case chain so I made a thread on that and someone suggested it could be a U-Joint. So I changed the rear U-
Joint and the noise was still there. So I got a friend to ride with me and was hanging under the car to try to pinpoint the loation. We got the vicinity and put it on the lift.

On the lift: Was turned off. Had it in P. Turned it on. W/foot on the break shifted to D. (Of coruse, it kicked into gear.) I had about 3 friends looking underneath. This is when we noticed it. I had thought the car was in 2 wheel drive. My friends told me that the front drive shaft was spinning and the tires weren't.:wtf: I looked and it was in 4H.:confused:

Now:
1. I hadn't been off-road or had any rememberance of any reason why I would have put it in 4wheel drive any time soon.
2. That means I had been driving it to the shops and back and just a lil to try and figure it out myself in 4H.
3. So when we put it on the lift, the driveshaft is fully extended. It wad still making the rubbing noise just in D. We looked at it closely and not the u joint but the piece holding it was rubbing to the piece attached to the 3rd member. (I can get pics back from it on the lift where you can see it was been rubbing.)
4. Now that means it is also rubbing when just being driven in 4wheel drive.
5. I hear that 4wheel drive isin't good to drive on the street in, but in the mountains, why shouldn't you be able to use the power you haeve?
6. Could this also mean I threw a pinion bearing.
7. Anyone got any ideas? Cause I'm tryin to get this fixed for good.

And , BTW, when you guys go off-road and your going up and over things (not fast of course but at that speed where you know should cause you can feel the suspension working) do you guys hear your suspension parts clanking and clicking and the like? Mine does it and it just makes me think. Does it matter because I have leafs and not coils? Also the same with speed bumps. Hitting them normally to just roll over them it kinda has that jerk in the front end that the back doesn't. What it that?


Sorry for a lot of information but I need to get this 4Runner fixed for good and a couple of these questions I think about I want to ask some people who aren't going to look at me like I'm stupid. I try to explain so people can get what I'm talking about.

Aright guys, thanks for reading. And input I appreciate. :)

Yeah, pics, because "the piece" is akin to saying "that thingy over there"...

How does it sound now that you put it back in 2wd? is the clicking gone?

Do not drive in 4wd on dry pavement. you need to have a differentiation in speed between the front and rear axle.

BUT, since your hubs weren't locked in, I doubt you did any damage. Just for kicks, grease all your u-joints... and check the level/condition of your diff fluid. Also, how dry is the slip splines on the front DS? unbolt the pinion end, separate the driveshaft halves, and smear SOME (not a ton) of grease on the splines. Mark the shaft before you separate it, and put it back together in the same orientation.

6. Could this also mean I threw a pinion bearing.

Grab the axle end of the front driveshaft. try like hell to shake it. It shouldn't move.

BTW, when you guys go off-road and your going up and over things do you guys hear your suspension parts clanking and clicking and the like?

Squeaks, rattles, and pops from frame twisting, yes. Clanks and clicks, only from the locker in the front.

What happened to that video you uploaded? I never got to see it.

My guess... something in your driveshaft.
