OK, I just typed a four paragraph response and got kicked off the forum (GRRRRRR!) because suddenly I was not logged on (after logging on five minutes ago!
I can't remember my complete thoughts I had typed, BUT in a nutshell, you need gears.
On the Zuwharrie forum, NC trailseeker had a set of 5.62 diff gears for sale. These are what you want and need for this truck (IF you bought it).
http://bbs.zuwharrie.com/content/topic,131743.0.htmlBoth of these diffs would install into the axle housings of the '95 Sidekick. The back would be no issue, other than the ring gear on the 5.62 has 10 bolts and your truck has 12 bolts. No big deal.
On the front, the 5.62 diff has 22 spline side gears. The Sidekick you are contemplating buying has 26 spline sidegears and CVs. So you would EITHER have to remove the 5.62 ring and pinion and install it on the '95 diff OR take the 26 spline side gears from the '95 Sidekick front diff and install them into the 5.62 diff and toss (or sell) the 22 spline side gears in order to run the 5.62 gears in the front of that '95 Sidekick. Honestly, it wouldn't hurt a damned thing if you had both the diffs rebuilt simply because the 5.62s are from 1989, so they have some miles on them. If the teeth are good (and I do believe NCtrailseeker is an honest guy) having them rebuilt would be worth it. I JUST rebuilt my rear diff that had at least 200K miles on it. The gears DID show the miles on the wear of the teeth, but they are running just fine with the rebuild. Do it once and do it right.
With 5.62 gears in that Sidekick, you would constantly catch yourself with a really stupid grin on your face while driving it and you would have a usable 5th gear too!
The ONLY other option you would have (to my knowledge) is to buy a NEW set of ring and pinion gears from a company called 4X4art which is located in Turkey. He sells his 5.71 gear sets for right at $1,000 to your door. One of our forum members purchased a set of his gears last December. When he opened the package, he discovered a set of gears that APPEARED had been mounted and possibly run in a diff. He was also having problems pressing the pinion bearings onto the pinion shaft. I don't know if he ever got them installed or not to date.
So my point being, at $900 this set of gears NCtrailseeker had for sale may well be a great deal. I DO know you rarely see them (5.62 Suzuki factory gears) come up for sale on the market (within our forums). I can recall three sets within the last seven or eight years, personally.
OBTW... nice beard and mustache pics. I've had one growing for a few months now too. I'm going to see how long I can get it before I start stepping on it and falling down.
