Limited Slip

[Mr. Stroker]

Ok, I posted a picture of my trucks burnouts on another site. Well one smart A$$ said, O yea you gotta do two burnouts in a ford to see if its got posi, weird how that works... Even tho i could care less and i did two of em cuz i wanted to. But since then my thread has been hijacked and it turned into a differencial talk. Kinda made me mad but o well....

But anywho, One kid has an exploder, he says he has and i Quote " i have limited slip/ posi."

OK! Now lets get this straight lol, my dads truck has the so called LIMITED SLIP! as well as all his other trucks, this one we still have the original window sticker that says it right on there, but it dont matter wut the heck hes got going on weather the chip is up and hes on a straight road and takes off spinning, one wheel, he sometimes has two of them spinning when hes in gravel and going straight. But he could never be able to do what is in my avatar, it would go to one wheel.. Now can someone explain? Or does this make no sense cuz im freakin confused..

I dont really care what i have, i dont use the truck for HEAVY off roading, and crap like that, but i just dont wanna go into the conversation with me not knowing wth im talking about lol.

A limited slip differential works off of clutch discs to let one wheel turn at a different speed when cornering. With age, the clutch discs wear out making the diff act like an open diff.

 

[Mr. Stroker]

gotcha, well with 145K on my dads truck im sure that its probably wore out. Even tho its a Dana 60. My truck only has 76K on it so obviously judging by the pics im still good lol.

 

[surewhynot]

Yup. They can be rebuilt though.

 

[Mr. Stroker]

Ok kool thanks man

Yup. They can be rebuilt though.

A person can also get thicker clutches when rebuilding an LS and give it better holding ability, love the Trac Loc that I stuffed in my '93's 8.8

 

[surewhynot]

Or just shove an extra disc in. I've done that on 9 inchers

Okay I've read a lot about the different type of differentials but I still don't know EXACTLY the difference between them all... When I had my gear swap done, the guy used a Ford Trac-Loc differential... Is Trac-Loc the same as Limited-Slip in the way that it operates? If not, which is a better system?

 

[1970Custom]

That too, if I don't swap the 9" into the Bronco I'm going to go on e-bay and pick up another $50 LSD out of an Exploder rebuild it and add an extra clutch disk.

One and the same

 

[surewhynot]

Yes it is. Trac loc, posi trac, sure grip are all different names for limited slip (clutch type) differentials.

 

[surewhynot]

Poli Grip however is not a differential. It is what holds Brad's teeth in.

 

[Skandocious]

Okay so the actual limited-slip mechanisms inside work exactly the same? Just different aliases? Cuz I've read on websites that they are built differently...

Hahahahhahaha reps for that one

Ha HA beat you Tony.


Overall they work pretty damned well, I've punished the one in the truck and it still does very well, if you're not playing in the gumbo mud or massive boulders they are awesome.

Just different aliases?

Just like posi is a GM term... they're all clutch actuated.

They are built differently but work on the same principal. Clutch discs, or cones apply friction to make both wheels turn at the same speed when going straight, but allow them to change when cornering.

Some are gear driven, some are clutches. Gear driven don't wear out, which is a plus. They also don't require friction modifier IIRC.

Or you can just weld it all together and never lose traction!



...until something really...really expensive breaks...

 

[surewhynot]

Just to add to that. The gear driven ones work like a ratchet. That is how Detroit Lockers are.

 

[1970Custom]

I was going to say, isn't a gear actuated LSD a locker?

Quit beating me Eric.

Hey, at least we both are knowledgeable in rear ends...
