How to tell if your car or truck has a limited slip differential

1. What if my posi rear does this with the wheels spinning opposite directions? Bad clutch pack? Not enough diff fluid?

2. Will only one wheel spin on a limited slip rear differential? I have a 96 s10 2wd and I jacked the truck up and spun one of the rear wheels and it spun by itself and the other did not

3. Chris fix does it have to be in Neutral ?

4. There is an awesome posi called a Torsen … very expensive and confusing on how it works … there was a wrecked 71 Mustang at the junkyard and I was going to buy the complete 9in rear end out of it, I turned one wheel forward and the other one went backwards , so I said damn it's not a posi , but I bought the entire rear end anyway and when I got home and took the pumpkin out I noticed it was weird looking and I had never seen anything like it , I found out it was a Torsen… a long time ago they were known as a Gleason Torsen.. so in other words just because one wheel goes forward and the other one back does not mean it's a one wheel Wonder

5. I have a dually 06 f350 and on the door it says it’s a slip differential but the when I tried your method the tires go the opposite way. The truck only has 53k miles. I’m so confused. Any ideas on why it’s doing that?

6. So if my truck has an open diff will it look like it does in this video? And if it is limited slip both wheels will turn the same way?

7. Hey your spare tire rim is very rusty 🤔🤔👎🏼⁉️

8. I have everything I need to change some rear axle shafts and change the diff fluid and I kept wondering whether or not is it a slip or not.
   Thank God for this video, thank you Chris!

9. what if it is a torsen diff?

10. my uk ford ranger is lsd but the wheels go in opposite directions.. Whats that all about

11. I have a 2014 MX5 auto .. I kept it on P, and jacked it up and did it .. and it went opposite, so it means that it's an Open? .. But most forums say that some LSDs are opposite .. shall I change the oil with the LSD additive? Or will it damage?

12. None of this applies to the g80 rear differential

13. Had my tires rotated today on my 84 Chevy Blazer 4×4 and noticed that it's not limited slip. But recently changed my rear and front differential oil and put in synthetic limited slip. It wouldn't hurt my differential would it? I don't really think so but still would like someone's opinion. 👍

14. Same rule does not apply for torsen diffs…

15. But can you swap a LSD in truck with a open diff

16. Searching up lsd rear axles and how they work… saw Chris fix vid and was like yep this is gonna be good

17. what if I spin one tire and the other tire doesnt move or sometimes moves a little bit?

18. Maybe another way is on Jack stands in drive/1st gear, stop on tire with a block of wood.

19. What would it do if it were a LSD? What would it do if it were an LSD with worn clutch pack discs, or improper fluid (sans friction modifier)?

20. Wow.. so much rust on your spare tired :O

21. chris where are you in jersey !??? p.s. not a stalker

22. I was doing a rear brake job on my 94 F150 with LS. Turned the tire and noticed the other one went in the opposite direction. Then I realized it was in park. Scared the crap out of me…Put it in neutral and realized it was fine…

23. Both wheels are turning clockwise but are also turning opposite of each other. Non Limited Slip Differential (NLSD)

24. Who’s here in 2020

25. Thanks!!have a question. I have a 2001 3.0l ford ranger not 4×4.what type of rear differential fluid do i a need to put on it.cause i have 2 new lucas 75/140gear oil..thanks

26. Or just do a burnout😂

27. So, what does it mean if the other wheel doesn't spin at all in either direction?

28. thx man ,am Lucky we have a similar truck

29. What if I spin one and the other doesn’t move at all

30. is a mechanical limited slip differential safe for turning corners?

31. Hey Chris, I enjoy your videos, I have a 2003 ford explorer v6 eddie bauer 4×4 that I want to do a differential fluid change, I lifted the 2 rear wheels of the ground and I spone the tires but the other one does not move. And when I go to the other side same thing I spin it and the other tire doesn't move my tag reads this 355 88 3e23 if you can help I would really appreciated.

32. what if you lift it, and one wheel spins along with the drive shaft, but the other one doesnt spin at all?

33. Hi chris got 1 ? For you how can i find out what gear ratio i have if my diff doesn't have that little metal tab

34. Hey Now!!!!!

35. Very informative answered all my questions. Thanks

36. This video is overkill. If you bought the vehicle new it will tell you on the window sticker under standard equipment or optional equipment.
    Also a quick burnout will tell you. 1 or 2 marks

37. You gonna add some lockers?

38. So many un educated replies. Ask 10 dumbies the same question and you'll get 10 different answere with no knowledge behind the answers.

39. The correct analogy is it's an open carrier.

40. What a transformation your videos have went through

41. Thanks, I will do this. See a guy post 3 rear dif from 67-69 Camaro.

42. My tag just says 1846?

43. So nobody is going to comment about the stock jack hes using?

44. What is main Racing Differentials

45. Ok Chrisfix now I know how to determine a limited slip differential and non limited slip differential,very nice video tutorial Chrisfix,ur video tutorial helps me a lot because I am a automotive student,for me ur a very good mechanic instructor.I wish I will be ur mechanic assistant someday.😀

46. Hi Chris, is it safe to use limited slip oil in open diffs? Thanks

47. Wow your videos have evolved…..IMMENSELY!!

48. I believe this is untrue. A differential will do this regardless. A limited slip will only engage once one side begins to spins to a point the locker in the diff engages THAN both sides are engaged forward. At least this is true for my 2001 S10.

49. My Infiniti qx4 has LSD labeled on my rear diff and I felt it kick in and grip up when I power slide in the water

50. y does da tire turn da opposite way?
