noisy turns in Hilux

Gday Bud
if it happens when on full lock mainly in 4wd & sounds like clunk clunk clunk clunk it is a fair bet that it is your cv joints need replacing

If it is a single clunk coming from under your feet its the leaf spring moving on the shackle. Also owned a 94 hilux did the same thing. Check the shackle bushes out but I don't think you've got anything to worry about. My hilux did it for years.

standard. why's that?

check the body mounts they sound like someone hitting the floor with a hammer.

Don't rely on them being fine "for years". Get under there and check. Sounds like the rubbers that isolate the diff are wearing out.

Metal on metal clunks are ALWAYS bad news and should be fixed.

I had a very nasty experience in an old Yota after the pin locating the diffs to the springs wore through/snapped off (dunno how and it was a very rough road).

Having your diff suddenly move either backwards or forwards a foot and a half is not good...... Not good for your tailshaft to drag out either - especially the front one which can dig in.

I have a 94 Surf which I think would probably have a similar steering set up to your Hilux. There is a rather primitive method of restricting how far you can turn the steering, it is litterally a bolt that comes in contact with another sloped piece of metal (forgive my use of technical terminology). Normally the bolt head has a heavy duty plastic cap which funnily enough wears after a few years, resulting in a rather horrifying bang, clunk, rubbing noise. The first time you hear it you expect something big to drop off and dollars signs start rolling round in your head. It is quite common, and can be cured by simply whacking a big dollop of grease on the offending items. There are 2 on each wheel, (for left and right turns), you cant miss them. Hopefully that is all it is. For all Toyotas well known engineering capabilities, its astounding that they use such a primitive method of restriction. New caps are available apparently, but grease lasts for several months and can be topped up whenever you need.
