Hello all(my first post) I recently have had my mustang lowerd on springs(with anti squat brackets to boot) and had a trak-lok(posi-traction) limited slip differential installed on my 2005 v6. My tires are still stock. Is it typical for you to hear a rubbing or skidding sound when you take sharp corners at low speeds? If so is it the sound of the Limited Slip Differential aka clutch chatter, or is it the outside tire skidding off the ground? Is there anything I can do to remedy the sound if its not infact normal? I'm positive the sound is coming from the rear of my car and not the front, and also I haven't been able to find any spot where any of the tires would've rubbed off the body(perhaps it hasn't made any visible indicators yet...but I've driven it quite a distance with the springs ang t-lok). Please don't respond with brandX is better than T-Lok, I'm not really looking to buy another Limited Slip Diff right now. Thanks in advance for any suggestions or help.
Hmmmm.... does not sound normal... perhaps they forgot to add the friction modifier? Friction modifier helps the clutch plates slip when you go around corners... http://www.drivetrainspecialists.com/categories/posi-service-parts/products/product-5224.html (BTW.. posi-traction is a GM term for their LSD)
I was thinking something along the same lines, which is why I'm going to try to add some friction modifier to the diff this weekend. The wierd thing is, at another forum I was told all the noise was normal so I came here and signed up for a second opinion. The only reason I use the term posi-traction is because some people simply only refer to LSD's using generic terminology.....kind of like kleenex and tissue. I used it in () for this reason....I understand its a GM part, and I meant no association between the two brands. Anyways thanks for your respsonse. Now I just need to find a place around here to get some friction modifier, otherwise the car is going to sit for a year without.
Should be able to get some at your local Ford dealer... I also would think a good auto parts store would carry it...
Just had mine installed a couple days ago. I have no noise and I bought the recommended ford racing friction modfier(2 bottles because Ford Racing states that 4 ounces is required yet one bottle only contains 3.8 ounces) let me tell you also that is some smelly stuff there. Anyways, I had royal purple 75-140w also put in. She's been quiet (except once intentionally ) and no noise at all. Summit racing sells the stuff for $3.50 for what they call 4 ounces but the bottle calls 3.8. They have extremely fast free shipping also.
Thanks for your advice. I dunno if I'll be able to have it shipped in time, even if the shipping is fast, this option may leave me with very little time to work on the car and fix the problem...if its more serious than needing lubricant. I'm going to get some 75-140w soon though
For me in VA BCH, VA any order done by 6:00pm eastern is shipped that day and is always here in 2 business days!
This does sound like a lack of friction modifier.. try to do this as soon as possible so you don't damage your clutches.
Definantly! I think I found a place in town here were I can buy some modifier and while I've got the car on jacks I might as well drain it and put some fresh gear lube in it too. Now all I need is some free time. If I'm lucky I'll be able to do it tomorrow. Thanks again everyone for being responsive and helpfull, most other forums aren't like this. I'll let you all know how everything goes. Hopefully I don't go to drain the thing and see a bunch of metal filings come out with the oil.
Well I drained the old lube that was in there and it smelled horrible. Made me want to vomit. Then I put the plate back on the diff and added some Trans-x synthetic gear lube additive and some synthetic mobil 75-140W. Then I drove it out the bay I was working in and it still made the same noises its been making. Then I drove it around and went and got something to eat and realized it stopped making the noises after I made a few turns...I think the problem is all fixed. After a few days or so here I'll know for sure... Thanks again for all your support guys. ~Cactuar.
Yeah my install guys told me the only break in for mine would be a couple s turns to get the differential lubed up and off I go!
