i have an 88 yota with ifs that when i lock both hubs an roll forward or backwards the front end makes a clucking  noise but with the hubs unlocked it does fine. got any info?

[Goldrush]

mine does the same thing, but only when i turn. i have a 90 4runner. pretty sure its just your u-joints, but not entirely sure.

mine does it when i go straight

Could be a number of issues from worn diff mount bushing, control arm bushings, a bad CV, a bad ring gear, might have a lunch box locker in it, possibly bad u-joints but not likely.

Lift the front end up, lock in the hubs, turn the wheels and see if you can hear where the clunk is coming from.

Does it make the sound on both pavement and dirt, or just the pavement?

Do you here any noise when taking off from a stop, or w/a hard stop?  If you do that is usually a sign that the control arm bushings are shot, not uncommon w/a 20 plus year old rig.

no sound when taking off or hard stopping. yeah it still makes the clunk on dirt an pavement. whats a lunch box locker? do you mean like a lincoln locker

[Snowtoy]

Lunch box refers to auto locking differentials, since they are cheaper than the selectable lockers.  I have one in the front of my '91, it makes all kinds of noise when the hubs are locked and everything is in good working order.

As mentioned in the other post just start looking into the front end, and see if anything is loose or worn.

I bet its the control arm bushings, Cut off that ifs and SAS it!
