Xterra diff ratios

[Barry]

I was trying to figure out which diff can go in which car to upgrade to locker using second hand parts etc. and found this, some people may find it useful.

Thanks for the info @Barry. Please guide us to the best locking mechanism also. I believe everybody is talking about rear differential lock. Kindly advise us about the front differential locking mechanism too if its possible in the XTERRA.

@Thomas Varghese what @Barry has posted is regarding used second hand parts. Since Xterra never came with front lockers there is no solution using second hand parts. Maybe you can do some research and start a thread for front diff-lock options on the Xterra. ARB offers some diff-locks and could be interesting to explore that option.

Second hand or not do we require another thread? Its anyways about differential lockers. Whenever we get stuck within 5 minutes we hear this question do you have differential lockers? I didn't see much help from the rear differential lockers. After doing some research I found out rear differential lockers only offer limited recovery options whereas front differential lockers offer a wider advantage. And I have gone through @Barry's very technical advices and liked them. So I prefer to have the discussion here. If @Rahimdad feel you need a different thread you can initiate one as I'm not very familiar with opening one.

The ABR is the less sophisticated option as for the rear diff locker in Xterra . However for front I have no idea 🤷‍♂️

Regarding diff lock options and which is which is better for which situation I found this link useful

Even I have no idea but some other car brands have it. If they can have why not we Xterrians? Probably someone has heard about this. That's why I asked this question.

I also posted the same. You also must have thought how to fix one on our car.

Sorry for offending you @Thomas Varghese to ask you to research and post a new thread. My idea was not to offend you but have the information on a new thread so it will get more traction. Since the first part @Barry posted highlighted using second hand parts for rear difflock and most people would read that and not continue, I was thinking a new thread would get the right traction. My apologies again @Thomas Varghese.

[Thomas Varghese]

It was not at all offending rather I said you can initiate a new thread as you are more familiar with the website. I'm just a newcomer here. I would appreciate if you can start a thread so that so many Xterrians can be benefitted. I would be thankful and grateful to you if you will do it. 
I was going through the forums and saw an interesting thread by @Barry. The reason I got interested was recently my front differential was smashed by not reverting back to 2W from 4Hi after a drive. The mechanic gave me an explanation for the delay that the 1st differential he sourced from Sajaa didn't meet the original ratios of my car. I thought he was fooling me. If you study this thread it clearly states Nissan kept experimenting on different differential gear ratios over the years on different variants.

If a rear differential locker not provided as OE for a car can be retrofitted by a third party vendor why not the same applies for the front differential as well.

@Rahimdad I would consider it as an honor if you will initiate a thread for this.
