The diffs on the D3 are tucked up in the chassis so the have HEAPS more under clearance than a normal off-roader.
The coil sprung versions are basically D2 suspension,but with the added undercar clearance as the diffs arent under there.
If followed Gordons D3(GGHaggis) offroad on several trips,the clearance is very good for a stock standard vehicle.
Im guessing you parked next to a D3 with air suspension,yes when parked they are lower than normal offroaders.

I don't understand this.

Diffs are at the centre line of the axle .....aren't they?

axle height is only determined by wheel/tyre diameter.

how can the diffs be 'tucked up' in the chassis?

I can understand this if there is a portal drive.

interested, not being argumentive.....

That would be the case if they had solid axles. They don't.

It took me a while to get my head around the idea of a diff that was fixed solid to the chassis or motor etc.

Very different to beam axle housing. Every wheel has its own CV and is independent.

something to learn every day.

sooooo, are owners lifting their d3's/4's?

if so , what effect does that have on cv joints?

are their any cv joint problems with these vehicles?

We have a selection of ride heights at our fingertips,then there are the GOE improvements or LIAMS improvements.
Then press the button and normality resumes for factory on road performance.
No need for suspension lifts

Because they are "true" CV joints there should be no problem. If they were el cheapo Hooke joints (the normal UJs) ...these are not true "constant velocity" when the angle of alignment is outside a very narrow range, hence vibration and other problems. That's why serious lifts do better with "double cardan" joints (two UJs joined together) in the drive shaft...

After reading GG Hagis' GOE manual it seems driveline failure is less likely on a D3/4, RRS, RRV with TR than a defender or earlier disco/RR. The electronic wizardry works the TR, air suspension , TC & variable centre diff lock/control to prevent excessive stress on a particular point on the driveline, and continue forward/reverse motion.

The answer your seeking Harry is yes, quite a number of D3 coiler owners have lifted their Disco's with very good results off road. One good thing about it is its pretty affordable to jack them up with a spring kit.

The downside is its always jacked up.

I will PM you with the contact details of a member who has done this, he might be able to point you in the right direction.

I do agree with Bob it would be a good idea to ask this question in the D3/4/RRS section, if you like I will move it for you?

Noo, if you have a d3 coiler you don't, didn't you understand this thread is about coil sprung d3 only?

**harry** · 14th January 2015, 08:16 PM

Thanks Terryo, this thread should be moved, and thanks for the pm.
Downside of a lift is permanant, as it is with D1/d2, only air owners get that luxury, thanks.with this car I have no desire to go off road, but I do want to be able to go where a commodore can't!
