What locker do you have? Mechanical locker add some movement in the drivetrain.
Yukon Grizzly 8" 4cyl. My first time dealing with a locked differential..starting to think it's my inexperience that might be the issue here.
I believe Blackdiamond is correct.A Detroit Locker will have 1/4 to 1/3 of a turn in the driveshaft.I'd bet Yukon would tell you that 5/8" is perfectly normal.Gnarls.
Regardless, I think I need to call up the folks at Yukon and verify this is perfectly acceptable.
My grizzly definitely has more backlash than both the trutrac and the factory carriers that preceded it.
Again, im a total noob to locked diffs..but I have to say after hearing the opinion of the guys at MC and on this board, I'm equal parts relieved and disappointed. The drive behavior (mainly the throttle) feels so sloppy now. It felt like it was marketed to be a much tighter and seamless system than I'm experiencing IMO. Alongside the overhaul of the rear end, I also dropped a fully trussed & refreshed front end with an aussie locker. Didn't occur to me until today I could compare the two....with hubs locked in neutral the Aussie has just about as much play. Though in 4wd the thing hardly makes any noise. Especially in comparison to the grizz. Lesson learned, I guess.
I run an Aussie in the front of my ‘89 SAS and a Detroit in the rear. Crazy enough I found out after more than 15 years the Detroit was missing a thrust washer that was essentially the difference between the old school No Spin and the newer Soft Locker. It’s much smoother now. It is all about driving smooth particularly when cornering and particularly when going slow. Have you had it load up and snap back together where it sounds like an axle just snapped? That’s where the fun really starts!
I have had people ask me if my truck was broken after my detroit banged as I was turning the corner in the parking lot.
... Everything I hear is during coast>accel accel>cost.
My Detroit has never made the ratcheting sound, so I would not expect your “copy” to either. The lunchbox locker are known for the noise, but it happens when they are installed in the rear end.
If you are hearing "noise" during acceleration there may be something not right.The ratcheting can be caused by a differential in the resistance at the axle shaft - for example: via a tire... like one tire has a significant lower PSI. Or... a brake drum is dragging.If there is a clunk sound at the very beginning of acceleration (the slop being taken up) after coasting, that was normal in my rear end Detroit Locker.I don't recall a "noise" while driving normally, or accelerating normally.I do recall a mild clunk noise at acceleration after coasting depending upon how throttle I used.If you are really concerned, then you might want to have an expert diff guy pull it and check it out.As I remember, and it's been a long time... installing a Detroit Locker was a different procedure than installing a Lock Right.I did NOT attempt to install the Detroit, but I did install my 2 Lock Rights.Gnarls.
