I’ll need to watch that a few times.

It's very watchable though

Impressed with America’s answer to the white helmets motorcycle team. Think I’m getting it now

Marked a wheel on each axle and two rotations of the front prop turns the wheel more than one full turn and two turns of the rear prop turn a wheel less than one full turn

Better to turn the wheel and count the prop turns but it does sound like you have the wrong diff in one axle.

Yes, it sounds like there's a problem there.

Chris's post above suggests a very simple and direct way to check for mis-matched axle ratios. With 4 wheel drive selected, and the front and rear wheels of only one side of the car lifted (two wheels lifted; two on the ground) , turning the rear wheel through one turn should also turn the front wheel through one turn. This method, as long as the 4 wheel drive dog is working, avoids any calculations concerning the axle ratios.

Thanks il try that but aren't there only two diff ratios ?

I don't think you need to try it - I was thinking about the issue more generally.

I would say that you have already demonstrated that you have mis-matched final drive ratios. I would say that you need to begin thinking about which diff you want to / can reasonably change.

Surely the one to change is the wrong one? It's got to be easier to put an original axle back in?
Or are you thinking about changing just the diff.. is that even possible?

steve2286w · Dec 19, 2021

Sounds to me like the 3.54 diff in front which is the non original
They are simple to change albeit a bit heavy, did the rear in summer
Drain oil
Pull out halfshafts fronts need hub and stub axle removing first
Remove prop
Undo diff nuts
Have some support under diff to take weight

Agree with steve above likely a 3.54 in the front. A builder bucket is good to hold a diff nose down, stops it dribbling oil everywhere as it rolls around the floor.
You may want to think about putting 3.54 in the rear to up gearing for everyday driving. Not recommended if live in hilly area, do much towing or you are diesel.

Yes, this was my point about thinking which one you wanted to change.

There are pros and cons each way. Putting a 3.54 in the rear axle will give higher cruising speed, but poorer hill climbing ability, but may allow tyres with a smaller rolling radius to be used which might allow greater steering lock - particularly if currently using 7.50-16s. The front diff is significantly more work to change than the rear.

chrisstdt · Dec 21, 2021

I'd thought about changing the rear as it's less work

But she has 2.5 flat diesel so that may dull performance too much

She has 205r16 tyres

Il see which diff I can get hold of first
