GQ Nissan Patrol Diffs into a Discovery

**Skiboy** · 5th February 2010, 02:24 PM

Well done Dave to post here

We have a project with Nissan diffs on a RRC chassis (all installed) and currently building a Defender body to then take into comp work so sympathetic to your design ideas

One thing I do know is that you get drive line vibration due to the off set from transfer case to the centre diff in the rear - how are you going to address that? Would Love to know as we are yet to solve that

I'm hoping that with the combination of a nissan drive shaft, adjustable rear control arms and a correctly set pinion angle, it should all work

You should be right using the nissan drive shaft.

I tried the GQ rear.. worked ok but the vibes made me go insane.. tried DC shaft and still didn't work. But will suit offroad comp.. but crap on the highway.. reason why i ripped out the GQ rear and put LC in..

All fun and games

Yeap fun and games alright.

I'll just see how it goes... I pick up my ute soon as a work car so it's now not an everyday driver.

Cheers

Well it drives.

Needed a new exhaust system as the drive shaft wanted to go through the pipes as well as the rear drive shaft.

Pick up the rear driev shaft tomorrow.

Chirps 35"simex when braking with not much pedal, so looks like i have good brakes.

Otherwise much the same car as before, just taller...

Testing this weekend.

Dave - Will be interested to see your comments and issues/fixes after the test drive. We are getting close on our similar set up - finalizing some mounts prior to engine going in.

Anyway I was interested in your post re the rear control arms - you have the Nissan adjustable ones right - so can I ask how you made the chassis end of these attach to the truck? Did you fab something?

I have reinforced rover rear arms but there is no adjustment to be able to tweak the diff rotation/pinion angle. Hence looking at options.

I have snake adjustable ones.
I just made adaptors to the disco chasis mounts.

It works but i'm debating whether to cut the chasis and weld nissan mounts on.

Anyway, i really need to get this driveshaft and soem 31At's and drive it round for a week or so to suss the new noises.

Cheers

OK re the mounts - I was considering making some with rose joints at the chassis end so that have thread to adjust on. Then I saw your post using the Nissan arms.

Sure hope you post pointers on the sort out process as we will have to follow you down this track.

Re diff rotation - I take it you have tried to get the face of the pinion flange pointing directly at the back of the transfer case?

Are you now running just a Nissan tail shaft or do you have a double cadian joint?

I've tried to set it up so the pinion flange and TC flange are parrallel.
The adjustable arms should get me to be about right.

Drive shaft is being made at the moment, it's a tricky one due to the size of the nissan uni's.
I'll post more details of how it was made when i know!!!!

Its all a learning process.
I expect i'll have to do a bit more to make it all work properly.
