Does anyone know the difference between a 1510 and a 1512 lockright.
the 1510 is for the sierra but it also fits inside the Vitara 10bolt ctr. There is quite a bit of clearance around the lockright gears to the housing.

Also can the vit side gear be swapped with the sierra side gear.


cheers

[gregdixon]

the 1510 is a sierra locker. The 1530 is a sierra locker with couplers. The 1512 is a vitara locker. The 1532 is a vitara locker with couplers.
I have attached the Lockright application PDF for reference.

I think the 1510/30 come with cross shafts and the 1512/32 doesn't. Both have been fitted to vitara centers with no troubles. NinjaMoses has a 1510 (came with shafts) and I fitted a 1532 (no shafts).

depending on which US store you buy from they all advertise different ones for vitaras. Trail tough say a 1510 and RRO say 1512.




I will get it right after I edit this post 10 times

Some Vitaras have a 3 pinion front diff,
according to lowrange,
but mine is a 2 pin, and all others I seen are 2 pin.
Sierras 4 pin.
Maybe thats the difference in fronts.
I running the sierra spartan locker in my front diff, using sierra side gears.
But I reckon the vit side gears could work.

Rears are another story,
think you need a vit one, bigger diff than a sierra.

[christover1]

spline count for side gears is 22 or 26
that makes a difference wether you use front or rear sierra side gears.
Dunno if all this relates to GV or not

im pretty sure i have the 1512, and i didnt get any cross shafts

this is all i got in my box for my locker??

edit: miss read it, thought it said the other way round...."1510/30 come without cross shafts and the 1512/32 did"

[Built4thrashing]

Just to clear things up a bit both the 1510 and 1512 use the factory sidegears. And the 1530 and 1532 use lockright side gears.

I want to know the difference between the 2 that use factory sidegears.


The only differencd i can see in the diff ctr is that the Vit sidegear has a different casting to it. It has a outer wall around the sidegear where as a sierra has its teeth open on the outside.

Ill take a pic after to show what i mean.


Pulled this off lockrights website PDF.

Quote:

NOTICE REGARDING SUZUKI SIDEGEARS
Lock-Right models #1510 and #1512 are designed to work with the stock sidegears in the vehicle. Powertrax
supplies gears that mate with these sidegears. These units work exceptionally well except on vehicles with a
high amount of mileage and therefore worn sidegears. Rather than replacing the sidegears with factory gears,
simply install Lock-Right model #1530 or #1532. Lock-Right models #1530 and #1532 replace the factory
sidegears

[gregdixon]

You can run both lockers in a vitara center it is just the cross chafts why they are different numbers not any difference in the locker itself. Ninja moses is running a 1510 with vit side gears and that works well so it would suggests there is no difference in the lockers.

If some sierras guys could confirm if they got cross shafts when they ordered the 1510 would clear it up. I know thw 1512/32 does not come with the shafts.

[Built4thrashing]

I got new shafts/pins with the 1510 lockrights i ordered for the sierra.
cool if that is the only difference ill start building it. Now to get the spare diffs and have it all set for a swap over.

Are just putting it in the Vitara carrier and not the GV carrier?

[Built4thrashing]

yes putting it in the Vitara ctr and that will fit in the GV Carried. I hope. I was going to fit 5.12 diff gears also but i think they might be to low. gear calculators say id be better suited to use 4.8:1.

Factory size tyres are 235/60/16. Im running 225/75/16 tyres but may go up to 245/75/16 later these are only 8.1% and 12.4% bigger than stock.

What diff ratios were in the 2.0ltr SWB and Lwb vits? is what ive found correct?

what ive found is

1.6 Man is 5.125
1.6 auto is 5.125
2.0ltr man is 4.875
2.0ltr auto is 5.125
2.0ltr softop auto is 4.875
2.5 V6 man is 4.300
2.5 V6 auto is 4.875


these diff ratios are from the Grand Vitaras from 1998-2005

will search for Vitara diff ratios next.

I have found a set of 4.8's for my car but they wan't $880 for just the ring and pinions. They are from a 2.5L auto GV.

Hey Guys.....

This has been interesting reading..... I've just put an Lockright Auto-Locker into my '93 LWB Vitara.... Now I'm looking at putting one in the front of my Vit.
Trailtough site + lowrangeoffroad4x4 both list a 3-pin carrier Auto Locker for the Front of the 10 bolt R&P / 22spline Vitara Diff's.... as shown below. I gather this is a simple bolt in & off u go.... but I was thinking if the Sierra one (1510) is a option...... Which one can I use in my 10bolt / 22spline Front Diff or should I just the 3-pin one?


I assume that even though I've got a 2pin Diff in the front, that this 3-pin one will also fit straight in ??



Thanks for all good advice

[Built4thrashing]

What that is is a normal vit ctr with extra cros pin holes drilled in it. You dont need to do that. The lockright will and does work with only one cross shaft. Buy the 1510 sierra lockright as they are cheaper. the locking cups are identicle to the more expensive 1512. you just end up with some spare parts as the 1512's supplied cross shafts are not needed in a Vit/GV ctr.


hope that makes sense

[tomataface]

Hey whats the price on a locker for a 89 SWB vitara, i didn't think you could get auto lockers for vitaras

what is it a 10 or 12 bolt diff?
10 bolt diffs can use sierra lockrights
and i think the 12 bolts can too with small mods... ill know when i do mine.

[gregdixon]

You can use a 1510 in a vit rear center 10 or 12 bolt. Just the cross pins supplied with the 1510 cant be used as they don't have holes for the roll pins.

My 1532 (1512) didn't come with the cross pins. Only the 1510/1530 do.

Check out ninjamoses's build he has a 1510 in the rear of his car, as does shandy92(could be a 1512 from memory)

[rob_macca67]

Well, I just got back an email I sent to lowrangeoffroad in regards to using the Sierra 1510 Auto Locker & Side Gears in the front of my Vitara and their reply was......

I have never seen or heard of anyone installing a locker in the factory diff. We have always used the one we sell and I do not have an answer to your questions. We just order them in from TT. They do the modifing on thier end and we get them in complete and ready to ship.

Sean

So, I assume this sort of reply is common... but I would have thought this sort of knowledge/mod would be well known by the boys in the US ??

Greg.... I gather your are confident that using a Sierra 1510 Auto Locker in the Front of a 10bolt Vitara Diff will work fine ???
Using the 1510 will give me more options later if I want to upgrade my axles from the 22spline to the stronger 26spline axles by simply changing the gears in the Auto-Locker...... is this correct ???

I know for a fact you can install a 1510 Sierra lockright into a Vitara 10 bolt ctr. I did it and then fitted that to a steel carrier and that into my GV steel diff. The only differences between the 1510 and 1512 lockrights is you get the cross pins with the 1510.

1510 = $199US plus post ... about $230 AUD posted
1512 = $249US plus post ... about $280 AUD posted

thats with our current exchange rate and paypal exchange fees.

Well, I just received back an email from lowrangeoffroad in regards to the 3-PIN Front Locker for the Vitara. I was thinking of buying the 3-PIN Front Locker as I thought there might be a strength/weakness issue in the Vitara Front Diffs (I have a Steel one though). They don't have any currently in stock and might not for a month or 2.

So.... I'll go with Plan-B.... buy the 1510's for the Front and Rear. One of my concerns is the difference between the Vitara and Sierra Side Gears (see Pics) will the 1510 still work properly using the Vitara Side Gears that have the Edge/Lip around the Circumference??? I know that the 2 are the same (ie Diameter) if u measure from the edge/end of the teeth across.

(Vitara gears on LHS & Sierra RHS)

[rob_macca67]

PS: I'm currently running the Lockright Locker with "couplers" in the REAR and while I haven't done any real 4wdriving yet with them, my main focus ATM is onroad handling as this is my daily driver. To date, I found any cornering at medium speed, etc seems OK (ie keep the power on), but it's the slow speed (ie: in & out of car parks) that cause the most problems with the couplers as they appear slow to dis-engage.

[gregdixon]

I have never seen a side gear like the one on the left. What year car did it come out of?

[Built4thrashing]

The Vit side gear teeth come to more of a point than the sierra ones and tend to rattle about in the lockright. They still work ok but you end up with more play in the center.

Front locker wont effect onroad handeling unless you drive with the hubs locked.

It's out of a '93 LWB Vitara with the Front & Back being the same except for one being 22 & rear being 26 spline.

I've also seen the side gear in the pics on the LHS in a Sierra Diff as well (I have the centre sitting in my shed)

I didn't notice that... I will have a look again tomorrow

This rattle/looseness... How would that effect the workings of the locker ?? Would the rear end tend to titch a little bit more, etc

[christover1]

I think all 2 pinion diffs have the lip round the side gears.
I chose to use sierra side gears with no lip.
I know people with 2 pinion diffs in sierras, still running ok with the lipped gears.

The Rear Vitara 12bolt Diff (4-PIN) also runs side gears that also have this lip around the edge as well.....

christover1 wrote:

So, which Sierra's run this type of Side Gear w/o the lip and where can they be sourced from??

[christover1]

Front wide track sierras use 2 pinion carriers.
I think rest have 4 pinion fronts.
All rears are 4 pinions.
Must be from a 1.3 as 1.o side gears and diffs dont interchange.

I have some 26 spline side gears (from Sierra rears),
I was going to use them,
but stuck with 22 spline.
22 splines are front sierras

So lipped is not from 2 pinions, I learned something

[Built4thrashing]

just to confuse you a bit but i have found lipped and un-lipped geats in sierra fronts and in Vit diffs. doesnt seem to be any patern to where they wer used.
