Thread: My Bucking Bronco Diesel Series III SWB

Hello Chaps and Chapesses!

I have, what I think may be a common-ish problem with my 1973 2.25 Diesel suffix A Series III SWB, it bucks like crazy when I try to hold a steady speed on level-ish road.

It could just be Kalgoorlie, and its rather substandard paved roads, which dip and rise over storm drains and missing tarmac here and there due to heavy trucks/poor maintenance, with all these minor undulations making for a very uncomfortable ride...

I notice that when towing that this problem is almost non - existent.

Now, I understand that this is caused by the pitching motion generated by the short wheel base, heavy front end, stiff springs and mechanical throttle linkage....

....So, what have i done?

I have replaced the throttle return spring with a new one, and checked the remainder of the springs related to the throttle mechanism, and replaced them, but this has not solved the problem...so short of replacing all the springs and dampers....is there any tricks of the trade for making driving a little more comfy?

I have travelled a fair bit in a friends SI when in the UK, and it did not seem to have such problems.....

Any help is much appreciated.

To cure your problem, you need to provide a mechanical dampener to the throttle linkage to stop it resonating. The easiest way to do this is to rest the right side of your shoe on the side of the footwell to stop in bouncing up and down.
