Nissan Patrol 4x4 (Africa)

So as mentioned on another post, I changed my diff ratios to 4.375's. This coincided with the instalation of an auto locker (Lokka) in the front diff as I have a standard locker in the rear.

So, first impressions on the ratio change. The "driveability" or whatever that encompasses is definitely better. It feels like the torque has increased that makes in-gear driving better. It also feels a little smoother through the rev range, but that might just be some confirmation bias. What does seem to be better is the "float" sensation I usually started to experience at speeds higher than 130km/hr. I always kept the Patrol in 4th gear, as this seemed to make it behave better, and improved fuel consumption. 5th was really just an overdrive gear. But now I have shifted to 5th and speeds higher than the above mentioned is a lot more planted.

I don't seem to remember my fuel gauge moving so slowly to empty. But I haven't had a fill up yet, thus I cannot claim any difference in fuel usage up to now.

I am also very happy with the fact that there is no indication that there is a locker present on the front axles in normal 2H driving. The steering feels exactly the same. No steering heaviness or mechanical clicking at all. It is to be expected, but I wasn't sure theory and practice would be the same.

I haven't had the chance to test the locker yet, but will get to it soonest.

So for some objective measurements.
Before with 4.11 ratios, steel front bumper, roofrack and 33" skinny M/Ts acceleration was as follows (Drag Racer App):
0 - 50km/hr => 5.6sec
0 - 80km/hr => 11.4sec
0 - 100km/hr => 15.5sec

Now with the 4.375 ratios (the rest the same)
0 - 50km/hr => 4.7sec
0 - 80km/hr => 9.6sec
0 - 100km/hr => 13.9sec

When new and stock it seems the TB45 manual did it in 13.8sec. I'm sure with a bit of practice I could improve on my time, but I didn't practice on the 4.11s. This is obviously also not what these vehicles are made for, but what other objective measurements can be used while limiting the variables.

Hopefully I will be able to report back on the locker soon. As well as some new suspension that I have been waiting for 5 months now.

This project has actually been on and off as I originally started it in December last year. Due to our 2nd wave then and 3rd wave now it's going rather slowly.

I have been pulling out the original sound deadening and replacing it with some new ones. I've only done all the doors , the whole passenger side firewall and front and rear seat areas. I found some rust against the transmission tunnel. I suspect it was the aircon leaking water there at some stage.

So what are the effects thus far? Well, a decibel app pre and post (partial) installation read 3decibel difference. I cannot really quantify that result, except by saying it's definitely less noisy.

I would like to get rid of as much NVH and in-cabin noises as possible. Thus if anybody has advice or knows of known culprits and fixes I would appreciate advice.

Just a note on my previous post- I converted my auto lockers by removing the auto part. I developed a clunking sound right front after going back into 2H after some playing in the sand. The hub conversion fixed that issue. Unfortunately, it seems I have some diff oil leaking out over my cv right front. That new axle seal is obviously not doing the job.

Jy het nog nie terugvoering van die voorste diff locker gegee nie.

Vetrel bietjie...

Baie mooi met die vordering, waar kry mens die sound deadening?

Praat met anthony hy reel mooi prys op daai

Yes Ruan, nee ek het dit gekoop in Windhoek, so Anthony gaan verseker vir jou die beste raad kan gee. My grootste vraag was maar hoeveel moet n mens kry...Niemand weet hoe groot n Patrol se binneruim is hier nie. Ek het toe vier bokse gekoop, dit lyk of dit moontlik genoeg sal wees.

Die voorste locker:
'n Persoon ervaar definitief 'n geneigdheid van die voertuig om reguit te wil trek...maar die Patrol se kragbestuur maak dit rerigwaar 'n non-issue. Ek het nog nie enige geluide gehoor soos die locker sluit en ontsluit nie - dalk is dit die I6 se geraas wat dit vermom.

Ek het 'n rukkie terug langs die see gery in die pers sand. Nou hier by ons is dit sand wat baiekeer moeilikheid kan gee. Die strand het 'n baie skerp helling na die see toe gehad. Ek het seker meer as 1km so in 'n "broadside" (neus skeef in rigting van helling maar voertuig beweeg parallel met die helling) met my spore wat maklik by tye half tyre diepte spore maak agter my. Was nogal lekker - kon daar ook die nuwe diff ratios se verskil voel.

Andersins parkeer ek altyd met my gat see se kant toe. En baie keer as daar weereens n styl helling is, is daar ook n klein step bo soos die hoogwater die sand n wal weggevreet het. Hier kan mens voel hoe beide voorbande jou optrek in die diksand, selfs al voel jy al die gewig van die kar skuif na agter (wat gewoonlik ingrawe) weens die helling en step.

Dus soos jy hoor was ek nog net in die dik sand met die locker, ek wil nog bietjie klip gaan probeer. Dit is mos eintlik n automatiese un-locker - so wil sien hoe dit daar werk. Die voertuig voel definitief selfs meer bekwaam as tevore.

Ek is gewoond om op grondpaaie in 4H te ry (met al my voertuie), maar asg van die locker sal ek dit nie meer met die Patrol doen nie. Uit onkunde weet ek nie of dit moontlik n wiel sal gryp sonder waarskuwing nie. Maar die Patrol is nie my toerkar nie, so dit is ook die minste.
