Hi there- after a great saturday out wheeling I have decided that I need to start looking for lockers but I dont really want to spend a fortune- it seems the only ones any rover folks talk about are the air lockers, are there any other options? All of the other manufacturers seem to be geared towards domestic stuff and whats up with this spline business? what are they? what do they do? how many does a disco have? Thanks. | ||

Alexa I believe this is the ones that Scott had: https://www.expeditionexchange.com/tractech/ But I don't know much, so I will let the others take care of it. | ||

A Detroit is a great option for the rear. Your only real locking choice for front is a air locker or you are gonna have fun driving with a detroit up there. The expert on landrovers and lockers is hands down, Bill at GBR. http://www.greatbasinrovers.com/ He can set you up with pre-built pumpkins just to slide in and go. If you changed tires to larger you might want to consider new gears. Most people would also recommend new heavy duty axles with a detroit. If you just want to buy the detroit or ARB and do it yourself just call John or Ho at www.Expeditionexchange.com. -Leo | ||

Actually you can run the TT up front I believe. There are quite a few people here that run Detroit rear and TT front. TT is not a real locker, just a limited slip. There are pros and cons on both types of lockers. Leo is right about Bill at GBR, he knows a lot and builds the diffs more than anyone else I know. My thought is that the Disco driveline is not meant to be driven with an automatic locker on all of the time (Detroit and TT), and that the entire driveline can be subject to unneeded stress. However, many people do use the setup mentioned above. Instead I would go selectable locker this way you keep the way your Disco drives w/o the locker and engage it only when necessary. Everything is under your control. | ||

I run a detroit rear end and recommend that you only lock the center diff off road when absolutely necessary....and not when trying to take corners....the two locker combination makes for terrible turning | ||

Has anyone just tried welding the standard diff up ? This is done quite a bit by po folk in the race/rally world - since a decent LSD costs lots of cake. Jeff | ||

Chris, the center differential should only be locked when on a surface that is loose, like off-road, on gravel, on snow or ice (but be carefule on slippery side slopes). IMHO your comment on the two locker issue might be another reason to go selectable since yoy can choose when to lock a selectable vs the detroit is locked until it needs to unlock. Check out: http://www.bb4wa.com/articles/Lockers.htm Jeff, unfortuntely the centering pin for the spider gears is the weakest link in the standard diff and as a result would not be a good idea to weld the gears on the standard diff. Not to mention your rig is now a permanent trail only rig, which may be a good thing for some people. | ||

Hi Jeff&Brian I welded the diff on my '68 SIIA and it works very well offroad, but to overcome the problem of a permanently welded diff, I fitted a freewheel hub on the short shaft side of my rear axle. Then I just unlock the freewheel hub and use it on firm surfaces, in one wheel drive. However, this setup very dangerous and I stay off public roads as much as possible. Just a thought here from africa. | ||

Your vehicle is much--much lighter and likely the drive train does not take the same punishment, not to mention it is alos a completely different diff. As I mentioned the center pin in the Disco diff is a weak link and most avoid the welding technique for this reason and for the reason that you cannot run on road without busting the diff or your axles. Disco also do not have the freewheel hub. For a series it might work for offroad and is certainly inexpensive. I would guarantee issues with welding the stock disco diff. | ||

Alexa, are you in a D1 or a D2? If it's a D2 the TT front and rear option is viable. There are a number of people running that way with the D2 because of the ETC. Thats the route I am taking. Bill at GBR is the man. | ||

I am going to talk stock here, just to make things easy. Stock axles on a 94-98 D1 are 24 spline. This is the number of "grooves" on the end of the axle that mount into the differential spider gears. A stock axle shaft mounts to the center of the hub with five bolts that are clearly seen on the outside of a rear hub, with stock alloys you would need to take off the wheel to see them. The axle slides down through a seal in the housing and the splines mount in the differential. In the pic below you can see on the left where the axle mounts to the hub, the larger smooth part is located on the seal and the splines are on the right end.  In the picture below is a closeup of a spline end, not the same axle and not even for a rover, sorry.  |
