So I asked this question awhile ago and didn't really get any straight answers. I took it by Urban Landcruiser and they couldn't really place what was wrong either. It is a clanking noise that happens when I am braking or sometimes just accelerating from a stop. It sounds like something is loose and I feel the clank in my feet on the floorboard. I hope this a good enough description to get some ideas. Any takers?
 
U joint slop?
 
I had a similar sound when i first got my rig. lube up the zirks (sp?) on the drive train and it should go away.
 
Certainly do the basic greasing. Ujoints, zirks etc
If that does not get it then I would suspect a cracked bushing
in the control arms.
I had an explorer that ate through a transmission in 12k miles due to one.
Sounds like metal hitting metal, felt it in my feet.
Never could get a answer for it until it was too late.

What are the zirks?

The zerks are the grease fittings.

There is one located near the u-joint on the male end of toyota driveshafts.

You must be careful though, because if you pump too much grease in the shaft and then articulate the suspension, it can crack the t-case due to internal pressure from too much grease.

The best method is to pump some grease in the d-shaft, and then unbolt the shaft at the pinion flange and remove the zerk. Then compress the shaft and the excess grease will squirt out of the hole that the removed zerk leaves.
 
When I have "overfilled" the grease fittings on the slip yokes, is always has clung out of the yoke when driving. Usually noted by burning smells for the next day or so.
 
I just had a similar symptom and it turned out to be a worn DS relay rod end with a torn boot. At first it only clanked quietly and occasionally when I put it in gear and I thought it was coming from underneath my feet. check the boots on your rod ends and get someone to turn the wheel back and forth a short distance quickly while you lie down and look at them for play. Also, stick a screwdriver handle to your ear and touch the relay rod end while this is happening. You should be able to hear if it is clanking.

Have you ever seen a cracked t-case due to over greasing the d-shaft? I have always pumped grease in till the shaft just begins to expand. Done this to all my toyotas for the last 8+ years and never thought it was too much. Usally the grease slings out the yoke, so how can it keep pressure great enough to crack a t-case?

It is working its way out over time. What happens when you hit a sharp bump at high speed fairly soon after overfilling the shaft?

I've seen a driveshaft that became about 3" wider than normal at the neck due to overfilling with grease...

You are more unlikely to hurt a split case than the earlier one piece cases.

Filling the driveshafts until the expand a little is certainly not a good idea. All it needs is a coating on the splines.

Well, I can't say that I've personally seen one but IdahoDoug diagnosed his cracked transfer-case as being a result of this hydraulic action. I believe Norm Needham confirmed his diagnosis.

Try taking your driveshaft off and then fill the slip spline with grease until it moves. Then try compressing the driveshaft. You will soon learn that this doesn't work so well. The grease has no where to go, except out the spines which don't have much room for grease to escape. Most slip splines have a little hole at the end for all the compressed grease to squirt out. For some reason (I guess to keep contaminants out) Toyota decided not to do this.
 
There was a thread about this, and also on my decision to unbolt one end of the rear shaft and remove the female half for cleaning, including what I found. And yes you can damage the TC by putting grease in there with even a hand grease gun that can generate very high psi.

Junk, what is wrong with you man ... you know that with that many marbles packed into the frame rails, there would be no room to rattle together !!!

Ha ha, all in fun stuck, i know you can take it!

Compulsory Tech Content For True 'Mudders':

... When my front double cardan driveshaft was recently rebuilt, along with some other minor modifications one of the things the shop did was re-add that little expansion hole at the end of the sleeve yoke. They told me that they wont normally work on a shaft without replacing the release area/s; besides being safer for the TC and other components, its safer for the shop - a sort of fool-safe, I mean fail-safe for customers who persistently pump the shaft full of grease despite being told not to! Yes, the shop told me not to over fill or over pump the shaft - four to six squirts every oil change other than that, no more. I would think that the contamination concern is valid but much less so when the shaft is properly greased; seems like it would be a much worse problem when the shaft was dry and wanting to suck in stuff. HTH

Thanks guys for all the responses. Oh yeah turbo i can take it. Are you kidding? Have you seen some of the things dished at me. I can take anything at this point I will have to check my driveshaft out. The noise is starting to get annoying so I will have to do something about it soon. Im also thinking it might be something in the bushings cracking because it sounds like metal on metal.

Sway bar bushings?
 
:cool: I think someone already said something about cracked bushings :banana:
Let me correct myself.
In my old exploder it was the radius arm bushing that was cracked and would clank.
Could feel it with my left foot mostly.
The way I found it was to idle forward with the driver door open and door alarm disabled via rock in slider then fit brakes. It would clank.
On a cruiser I guess it would be the control arm bushing. (attaches to front axle)
Certainly could also be a swaybar.
Good luck
