I have a '92 Pajero and it's starting do develop that typical 4WD suspension creak when you go over bumps and whatever. Is there a common part that is replaced in the suspension of the paj because of these noises? ie bushes etc. What are other peoples experiences here. The sound appears to be coming from the rear but it is hard to tell. I guess I'll have to go through the whole lot and change every bush etc but other peoples ideas would be appreciated...



cheers

Logical question.
Have you given the rear end a good grease and lube? Pivot points, etc?

get a mate to bounce the car (Im fat so I usually do the bouncing on the towbar while someone listens :)~ ) while you lay under the car, see if you can pinpoint the area of the noise.. Then easier to say what needs to be done.

Being a 92 mod, have any of the suspension/shock bushes been changed? Is your model leaf or coils (not up on Paj's).. Same again leaf bushes, control arm bushes etc..

Suspension noises are ANNOYING ...Well any under car noise is annoying!

It has coil springs all round. I've geased all the grease nipples I can see and sprayed all the bushes with CRC. but it's still there. Yep they are annoying. Is there any common problems in this area with pajeros that anyone knows of ? The car had done 230k now so I guess I should expect some noise coming from it now. Is there a noticeable difference after polyuerothane bushes are fitted? I notice on other forums there are people asking about replacing their front torsion bars for stiffer units.Why? Is there that much difference. I had better find out about these possibilities before I jump in and replace bushes in case maybe I should be going a step or two further.
My car has upgraded shocks and springs in it which has lifted it up a little. For the amount of offroad work I do it is more than suffient.

Comments?
Suggestions?

Diamond may be the man for this one, he works with suspension....

Stiffer Torsion bars can give more lift...

Poly bushes, its one of them things, depends what day it is and who you ask! If the OEM ones lasted 11yrs, why not go them again? Probably pricey, but will last.

Maybe take the bushes out of ALL the links/bars and run some grease around them to see if that helps out, also on all the bolts on the mounts.

HTH.

Might also be the bushes that support the body on the chassis. Everyone gets involved in the "suspension problems", but forgets the chassis is in torsion in normal day to day use (potholes, etc.) with a body bolted to it. Try retensioning the body support bolts, might need new rubber supports too.

I had an L300 4wd van that sounded terrible (they're basically a shortened Pajero chassis). The guy I sold it to fixed the noises by spraying the pivot bushes for the control arms with WD40... It was an earlier model, but it might be worth a try.

Mike,

We had the same clunking noises in our '94 NH Pajero. We did all the things suggested so far...replacing bushes, greasing, played around with torsion bars etc etc. Even after a rear suspension lift, the noises remained. Never got to the bottom of it. Annoying yes, but not a problem otherwise.

thanks for the comments people. I think I'll start by doing the back suspension bushes and see how I go. I've tried all the obvious quick fixes so I better start replacincing things bit by bit. I'll have a go at lubing the body support rubbers as well and see how this goes...

cheers

Mik.
Just done a front end creak in a 92 it was the pivot at the rear of the bottom wish bone, just take out the torsion bar, take out the bush pin clean and grease and reasemble, note the white lines on the torsion bar line up with notches in the brakets, bingo. Eric.
