I had
mine done just before Xmas last year (94 model so there goes that theory). I originally took it in to address a worsening snatch in the drivetrain and, after some discussion, was convinced that it was the way to go. Not sure what brand of kit was used (will
check), but it cost around $1200 to do. I know that it will take a long time to make up the $1200 in any fuel savings (assuming there are any), but the repairs were going to cost me in the order of $1000 anyway.
Arguments for having it done are:
1. Fuel economy. I have yet to determine if it is better or not as I have had the CT off and on since then, injectors overhauled and a number of other factors that make an accurate determination difficult. My gut feeling is that there is some improvement, but yet to quantify it. In any case, there is some logic to the theory that less moving parts/friction must lead to greater efficiency.
2. Reduced wear on front drivetrain. I guess it could be argued that the additional power transferred to the rear causes increased wear there, yet I would guess that it does not increase by a factor of 2. I also have some slack in the front tailshaft spline which was (in part) contributing to my original problem. Now it is only apparent in 4WD (and then marginally), which I can live with.
3. The car feels better on the road and lighter to steer.
4. I am not sure what impact on tyre wear yet, but I rotate them regularly so should not be an issue.
Against:
1. Cost. But as mentioned repairs to the original configuration were about the same.
2. 4WD is always nice to have on gravel and I now need to remember to engage it. The centre diff lock button has become the 4WD select button and hubs need to be engaged. Of course, you have to hop out of the car to engage the hubs, but the kids are good at this now.
3. Centre diff lock. This is the big one, the kit I had put in takes the centre diff lock out of play. I have not investigated whether ($$$$) another kit is available to re-configure it, or whether other part-time kits leave the centre diff lock available. We mostly use our vehicle to tow the CT on gravel and moderate 4WD tracks, so this is not a real issue for me. However, if you are into the more serious stuff, then you need to
check out exactly what the kit you are fitting will allow you to do.
Hope this helps.
Matt.
P.S. Fuel economy and the 80 series petrol are not good terms to use together. Perhaps
mine has gone from absolutely atrocious to just atrocious.
