    My Detroit seems to have to much slack. The backlash checks out fine, but when I turn the driveshaft forward or reverse it turns about a quarter turn before it engages. Is this normal? My bud has one in his ford 9'' and he's experiencing the same thing.

    Any help will be appreciated.

    Thanks,
    Ric

    Yep, thats normal. The book that comes with the DL even says that the "slop" or "play" is very normal and nothing to worry about. All part of the design.

    Thats why I welded my 14 up, no slop[​IMG] very predictable handling, and a little easier on my budget....[​IMG]

    I've been thinking about welding mine based on what I know about DL. tRustyK5, how do you like running your welded diff with swampers?

    Its better with the Swampers than my General Grabbers. The Generals are radials though. Its a little chirpy here and there but for the most part I don't really notice it much. I sure like it off road though, now its just point and shoot so to speak. From what I have heard the DL's will chirp the tires in tight quarters too, so I don't think I've made a bad choice.

    In my experience, there is very little difference between a rear spool (or weld up) and a DL except in one scenario. Even on the street you don't really notice the difference that much. A little more chirping but none of the banging and popping. However, if you have allot of weight on the rear axle and *both* rear tires are firmly planted, it can be almost impossible to turn unless you have really good traction in front. This is especially true with the front axle disengaged. If you are nose up (with most weight on the rear axle and little on the front) you can give up turning if both back tires have good traction. At least a DL will let the outboard tire "over-run" the inside. Note that in the previous scenarios, the DL is only marginally better when the front axle is disengaged because pushing from the inside tire will still over-whelm the front tires with little weight/traction. With the front engaged however, it will help pull the front around easier since the outboard rear tire can roll instead of being dragged around.

    That one final point is the sole reason I will put a DL in my C14. Also, the DL for a C14 is a very simple install and much cheaper than any other axle (to my knowledge). In the C14 you can install it yourself in an evening with no fancy tools since you do not need to change the carrier.

    Just my opinion...

    Here is a quick question,

    If I weld up the rearend will I beable to replace the gears and replace it with a detroit locker later? Or will welding it up screw me into keeping the gears & carrier?

    Thanks,

    Corey

    Welding the spider gears will not prevent you from changing the ring and pinion. Assuming you have the factory 10 or 12 bolt, you would have to replace the carrier anyway to install a *real* DL. I think only the C14 allows the DL to be installed in the original carrier. However, welding the spiders will make it impossible to put an insert locker (lock-rite, etc.) into the carrier. This is because inserts replace the spiders which should be both welded together AND welded to the carrier to create a strong "Lincoln Locker".

    They don't make very many lockers for teh s/f 14 bolt, so I'm sorta limited in my choices. Currently, I'm only running 33's, but I have 35 TSL Boggers 16.5" wide for the truck also.

    Hmm, no idea about the 14SF. Anytime I have questions, I call the manufacturer tech lines and start asking questions. Be it lifts, diffs, intakes, headers, whatever. Just remember to take what they say with a grain of salt since "their brand" will always be "the best ever made". Anyway, if you do a weld up (essentially a home made spool), it's not that bad. Like I said earlier, in most cases you will not see much of a difference in spool or a DL. Mostly swapping pops for chirps on the street. If I didn't have a C14, I would probably do a weld up myself before spending the money for a DL carrier AND pay to have it setup at a shop (about the only thing I don't do for myself is set up a diff!). Putting a DL in most diffs only makes sense if you are also swapping gears (which neutralizes the setup cost for a DL).

    Oh, and the DL carrier is stronger than the open carrier...

    Thank you'll guys for the info!

    It's a great relief to find out its normal considering how much they run, hate to think that I would have to replace it.
