75 ser Landcruiser Ute springs........

Hey Reiner

Take it to another spring mob as these dip sticks should have told you, all you need is some shackle rubbers.

Try that.

Cheers Steve.

my 75 ute doesn't make a clonk; a lot of people seem to say 'they all do that'. a worn tie rod end does though, but you have replaced that. I'd get a second opinion about the front springs.

I have struck this is in quite a few HJ75's , nothing worse than the clonk when you cant be exactly sure where it comes from , and I do know from experience that you can drive yourself almost insane looking for it .

What I have found is by starting your engine , and with the drivers side open rest your fingers on the top of your front spring just in front of the rear pin on the flat part of the spring , and wobble your steering wheel from side to side just where you are getting the clonk, and you will feel (hear) the clonk , if it is the spring pack moving . Of course it is always better if you have an offsider to wobble the wheel for you

I struck this in quite a few HJ75 vehicles in the opal fields and the only way I could get rid of it was to replace the front springs , but then eventually the noise would come back , so we never used to worry about it too much on the dirt roads . One HJ75 of my own I removed the springs , removed the centre pins , and sprayed them with black fisholac paint then re assembled them , and they were ok for a long time , but the noise eventually came back .

I have seen this happen in a lot of HJ75's but not all , sometimes it is things like tie rod ends , relay rod ends , or shackle rubbers , you have to check everything , and I have never heard of it happening in HJ47's or any vehicle with unassisted steering , only it seems in power steering vehicles .

Reiner,
Hate to say it, but IMO "they all do that". Mine does it, new springs didn't do it for a little while, then they did it, new springs were reset later and stopped for a little while then they did it, my dadinlaws does it etc. Nearly only when the spring packs get wet though?? If you get down and have a look the spring packs squirm around quite a bit when turning.

So to answer your question, to get rid of the clonk, buy a new TD V8 70 series-its the only possible sensible fix :-))))

Gidday mate, I spent many years belting Cape York and most springs do it. If you look at where the front springs anchor to the chassis an look where the second spring leaf wraps around the main leaf you will see a witness mark where the edge of the second leaf wrap at the top has been contacting chassis, usally the inside. Fix is replace shackle bushes, check spring centre bolts (probably OK) and tighten U bolts. I have on occasions curled second leaf more and ground a little off corner edge. different spring manufacture use different thickness spring steel and sometimes curl second leaf differently meaning with different brands as bushes wear "clunk will be different, some worse than others.
