Hi Guys,
Have had a problem when reversing my Rodeo when in low range.
It shudders quite badly and feels almost like there are highspots on the flywheel or the clutch plate/pressure plate is warped and engaging and then slipping. It is much worse when the truck is loaded. This is strange because it only happens in low range.
The clutch action is perfect at all other times, no shudder,slipping or any jerking even when heavily loaded.
Any one else ever had this problem?

Check the ujoints in the driveshafts and that your rear springs are correctly tightened.
Does it do it when releaseing the clutch or does it continue at low speed with the clutch already released.
My lsd does this a little on take off forwards but nowhere near as bad as you describe.
You say this is in low Is this with the hubs locked and if so is it a hard or soft road. If its a hard road then any difference in tyre size will cause a tyre to jump as it has to slip. 4wd should never be engaged with hubs locked on dry tar seal roads in a part time 4wd vehicle. Gearboxes in lesser 4wds have been known to destroy themselves in this situation.

Hi Alan.
Thanks again for your reply.
UJ's and centre bearing have recently been replaced.
Yes, it does continue after you have let the clutch out completely and actually gets more and more violent (like kangarooing) where the whole vehicle "hops" under heavy load reversing up an incline.
Yes the hubs were locked on a paved driveway at the time I experienced it but I was reversing straight back so it should not have caused any problem I don't think?

Good point Alan,
I will when I next have a full load of building sand in the bin. I have a very steep paved driveway and getting up with a full load can be a bit hairy in rainy weather. This was when I locked the hubs which, in hindsight, must have put a lot of stress on the drive train.
This is clearly a disadvantage that I did not think about on the part time 4x4 drive configurations.
Thank you for you info again.
Boet.

In the wet there should of been enough slippage but its hard to know for sure.
I think Ive found my judder on take off forwards but need to fully look into it. The diff is rocking on the springs even though the bolts are tight. Possibly a bit of a worry

Hi Alan,
I do not understand how the diff can rock with the leaf springs securely tightened?
I removed my load bin to check out a sag in the chassis. I will be removing it again to do the repair and will sit on the back with someone else driving and see if there is any strange movement on the spring mountings.
Boet.

I dont understand either yet but it will make sense after Ive pulled it apart and had a look.
The bolts had come loose and been retightened 2 weeks ago. Maybe theyve come loose again Maybe there was mud in the gap that has since fallen out or maybe the flat plate on the bottom of the diff has bent. Nice job for the weekend.
