Body mounting bushes? (was never the problem)
Good day all,
A irritating matter i've got with my KZ....
When its cold weather or has 4 occupants it drives like a dream.
When its warm weather or when ive been driving for more that half an hour its starts to drive like rubbish.
Shocks and suspension bushes can be ruled out as they are not older than a year.
Engine mountings have been replaced and checked...still going strong.
The KZ has 448k km on the clock and my gut is telling me that body/cab mounting bushes needs replacement.
Any comments or alternative things to look for welcome.
Regards
Splitpin

Daniel, "drive like rubbish" doesn't tell me what the problem is. What does the vehicle do? Can't you keep it in the road or what?

Re: Body mounting bushes?
You say shocks can be ruled out but I'm not so sure ..... what you describe is typical of a hard shock absorber or one that is too heavy duty rated for it's application. In a case like this the extra weight of 4 people (or a load) smooths out the ride, or in some cases like with a purely hydraulic shock (no gas) there is a small amount of "fade" as the hydraulic oil warms up and becomes more viscous. The faded damping will then also give a smoother ride with an overly heavy duty unit.You wrote:When its cold weather or has 4 occupants it drives like a dream.

What shocks are in there? Are they adjustable? If it's Gabriel Safari's, I think that's your problem.
When your road comes to an end ...... you need a HILUX!.

Re: Body mounting bushes?
P.S. It's not the body mount rubbers - they get harder and compressed over time so their ability to absorb vibration does indeed lessen, but their function is purely vibration damping and not shock damping. Furthermore their characteristics won't change significantly enough with cold and warm weather. Then also, with an additional load of passengers they would tend to be compressed further which would result in less ability to absorb vibration, not the other way around.

Re: Body mounting bushes?
I can keep it on the road no worries, When cold it feels like a brand new vehicle, When warm it feels like a old worn out plaas bakkie.

Monroe shocks, not adjustable.....reading your comment makes a lot of sense, i once loaded 20 bags of wood and it felt like driving a car with air suspension.Mud Dog wrote: ↑Mon Oct 19, 2020 2:40 pmYou say shocks can be ruled out but I'm not so sure ..... what you describe is typical of a hard shock absorber or one that is too heavy duty rated for it's application.

Re: Body mounting bushes?
If you don't often load it then an easy solution is to load a couple of sandbags right at the back, not ideal for fuel economy though because you're lugging extra weight. Won't have a big impact but over time it amounts up - motor also works that little bit harder through it's life. Might be better in the longer term to consider softer shocks.
On the other hand, if you do often carry loads, then load the sandbags as ballast when there's no load.
Just thinking "out loud".

Re: Body mounting bushes? (was never the problem)
So for the fifth time work was done to the driveshaft. 3 times repair and 2 times rebuild.
High spots on a brake drum caused a vibration and I thought it was the driveshaft, after taking the driveshaft in I was told that the slipyolk was worn and needed replacing (1st rebuild) +- a year ago.
So after replacing the brake drum and having fitted my new driveshaft i was a happy chappy....
A few months later I started to notice some weird noise when cruising over 100km/h.As per my OP it got worse and I decided to get underneath after doing two 100km trips 2 days in a row. There was play on the driveshaft...and no not rotational play....side to side play. Being gatvol i took it in
A gent @ Ferobrake Port Elizabeth told me that the previous gentlemen that worked on the driveshaft took a land cruiser male side slipyolk and made it fit on the worn out kzte female side slipyolk.
I must say..for a gemors job they did it pretty good...and it lasted about a year. Anyway...all new parts were ordered...strictly KZTE parts....and a brand new "heavy duty" driveshaft was born....
Its happy days and my KZ drives gorgeous on the road...cruising along...no vibrations... There is a new noise which i believe is coming from the passenger side.
