I hope this one would be an interesting topic, I didn't see many similar pics on the net, and it may clear some of the blur about the factory LSD. As some of you already know, my LSD made strange noises and vibration on slow speed cornering and starting with the steering wheel turned, so we opened it and swapped in my old open diff. Here are some pics from the diff: And the flaws on the inside of the housing, that we believe is the cause of the problems:
What kinda damage did it do? Scoring? Reason I ask is I have a TRD 1.5 way LSD installed in my E153. Ocassionally when I take off with the wheel turned there is a clunkin' sound. Could it just be choice of transmission gear oil?
I just did some research. It actually appears that the clunking is a normal thing with LSD units...more later.
It depends on what kind of lsd. First I was told it's normal, but then why did it not do that in the past? (it started about a year ago). And as time went by, it got more and more worse, so it's not normal.
Mine seems to only do it at very low turning speeds. Everything I've read about the lsd clunk is related to gear oil apparently...
Interesting. Everything I've read says it's normal. Mine has always done it (since I've swapped in this motor and transmission w/ LSD). I'm running store brand LSD with some modifer off the shelf. It's time to upgrade to a synthetic gear oil now though (just like I'm about to change my oil out for synthetic).
I've never opened up my diff all the way. I will say this though. After I swapped in the e153 in I broke it in using the recommended gear oil (GL-5). I used a store brand dino GL-5 with a friction modifier. I had clunking at low speed turning, some take offs and reverse. Last weekend (or the one before) I swapped out the standard GL-5 gear oil for Redline MT90 and Ford XL-3 friction modifier (4 quarts Redline, 1 bottle Ford). It clunked once or twice after the first drive, but other than that I have not had any clunking. Shifting is also butter smooth when it's at the normal operating temps as well. Cold is another story, but warm it's awesome (also from talking to other e153 owners this transmission is known to be a bit stubborn when cold).
Crap, I've been told by everyone this far, that it's a helical one, and even on the MR2 board BEAMS forum they said that no special oil is needed, so I used standard 75W90 Castrol Damn...
Yeah the clutch style needs different oil. Standard crap won't do it. The only reason I ran it in mine was I had to flush out my transmission after tearing into it.
I have spoken again with my mechanic, and he said that the oil used wasn't indeed the best (he wasn't the one who put that in), but it cannot have done this damage, since the clutch parts are in great shape, only the housing has mechanical damage.
yeah clutch type. although being a standard Toyota diff you'd think that the trans would either be labeled or it would take normal (Toyota) fluid. interesting though.
VVT, Mafix are correct - you need to use 80w/90 LSD oil, it is a plate lsd. They are known to clunk for quite a while before the oil takes effect What I find weird is that this looks like an "S" series diff, do you have pics of the box? The "E" crownwheel has 16 bolts, yours only has 8 like on an "S" series. For pics of the Toyota MR2 LSD - http://www.st162.net/forum/showthre...a-162-2-amp-4-door-and-many-more-jdm-oddities Those gouges looks like dirt entered the diff thru the driveshaft shaft holes or something broke inside, inspect the internals very carefully - I found a crack in one of the pinions
Yes, I have an S54, and spoken with the Beams guys, my best bet that it's a TRD diff. I recall seeing that in the ad, when we bought the engine back in 2006 as well.
