Engine & DrivetrainDiscussions about the engine and drivetrain of your vehicle.
This is a discussion thread titled "This is a good one", within the Engine & Drivetrain forum, part of the Technical & Vehicle Assistance Forums category.
I was at the dealer picking up a latch assembly for the AC door window which broke over the weekend. While I was there I thought I'd ask again about a rebuild kit for the factory limited slip. The parts guy couldn't find anything so I asked if I could talk to a tech. He said I needed to talk to a service writer first. I asked one if there was a rebuild kit for the factory one but that I knew there was one for the TRD model made by Eaton. He asked if I ever had the rear diff serviced and I said no but that I just bought it and the guy had it serviced at this dealer every 5k miles and that it now had 55k and every LSD equipped vehicle I've had was worn out by then. He said I should service the rear and that it required special additive. He said the Toyota LSD was a lifetime product and did not wear out. He asked the guy next to him and they both looked at me like I was crazy and both said they'd never heard of such a thing.
That does not give me a warm fuzzy feeling. I'm now wishing I never paid for the the extended service contract knowing that I'd have to bring it to them. Since I'll be doing most of my own routine maintenance I can already see what I'm going to have to go through if something covered does break. Oh, joy!
It actually wasn't a tech but the service writer. I figure the tech is going to tell me the true story. Just because they haven't seen them come in doesn't mean a thing, in my mind. They weren't available as a option until 2002 and they usually wear out around 50k or so miles. Most people probably don't know a thing about the LSD and would never know it wasn't working to even bring it in. So, I doubt it really means anything other than they don't have a clue what they're talking about.
I would have looked at you the same way. I've owned 5 mustangs and they have all made it past 100K with no problems from the Traction-Lok(Fords version of a LSD) I think as long as the thing hasnt been abused or ran dry of fluids the LSD in your tundra will last well beyond 100K.
100k miles is not a lifetime part. The fact that they have never heard of a rebuild kit and stated that a LSD never needs rebuilding is asinine. They do wear out whether it's 50k or 150k miles. It's a clutch similar to a clutch in a manual trasmission. They wear out.

I was curious what vehicle you had that the LSD had to be rebuilt in? I worked for Toyota for 7 years before going to Lexus and have only seen the need to rebuild or replace if water got in it. In most cases it is cheaper to replace than to rebuild. I understand if you are running larger tires or racing, but the average person will never have any problems with normal maintenance. I have seen Toyotas with over 450k no problems with the diff.
I actually never did rebuild the LSD in my Dodge 2500 that was worn out at 65k since I traded it at 75k. I was just beginning to find out the costs of getting the parts to rebuild it or putting in an ARB locker in my Tundra.
Are you saying that the LSD's in the Toyota's you've worked on never wore out? The vehicle with 450k miles on it still had a fully functional LSD?
...the LSD in my Dodge 2500 that was worn out at 65k
Ah ha...........now I see your concerns.
I wouldn't worry about it though, it is a Toyota and I am sure we have many LSDs around here with well over 100,000 miles. Some probably approaching 200,000 miles, if it was a problem, it would be addressed here.

It might be worn but 99.8% will never notice. Since it only transfers max of about 70% torque when worn it might be transferring 50% and a litttle slower. Since most people will only realize the need for LSD in slippery (mud, snow, sand) conditions, even 50% will provide that added traction over an open diff.
Now, yes there are clutch packs in it but how often is it being used? Will it slip some around turns, yes, but normally no pressure is being put against it unless applying heavy throttle so not really wearing. Thinking along the same lines as the No-slip, under normal throttle it does not engage in turns. Going straight the no slip will lock as soon as any slip is sensed, the LSD will apply torque more gradually as the clutches slip but normally in a very short time will not be needed same as No-Slip. Regular clutches go over 100k and see a lot more stress everytime you start.
My dad had a '95 Dodge Ram 1500 318 V8 and 5sp manual. His rear had to be replaced at about 38K miles. He never towed anything (no hitch) and didn't haul much either. It was his daily driver to and from work basically.
It started to make a whining noise before being replaced.
