I've got a 9.75 H9 in one of my trucks...and in the last month or so i've noticed only one tire tends to spin in slippery situations unless I get the tires spinning REALLY fast....(like almost floor it)...It used to take alot for me to break traction....So with 178,000 miles on them, I'm guessing my limited slip clutches are shot....
Is it an easy job to replace them? and worth the expense? (Idk how much the new clutches normally run or trusted brands)

Or should I look into a detroit tru-trac gear based LS carrier? those run upwards of $600 from what I've seen and im not sure its worth dropping that into a truck I paid $1500 for.

Thanks in advance guys!

 

The clutches are pretty straightforward to replace and not expensive. However the don't work nearly as well as a trutac will and they will wear out again so keep that in mind.

 

It's time spent under the truck bed. Never done the clutch discs but I've done other stuff in there. Raise it up high, and get some bright lights and it shouldn't be too hard. You'll probably need to reset backlash if you go with a Truetrac, but with just replacing the clutch discs in a TractionLok hat's not a factor. Of course, while you're there, you should probably change carrier bearings. Discs is just swapping parts, the Truetrac is more involved.

Not an expert.

thanks guys

 

Truetrac is supposed to be great, particularly for street driving and icy conditions where regular LS will behave erratically.

Offroad......they are known to be somewhat weak. Considerably weaker than a stock differential.

Many people put a truetrac in, reuse existing shims, and no adjustments are necessary.

However, in addition to truetrac, you need carrier bearing kit, and you might as well replace axle bearings and seals while axles are pulled....easy and cheap. To check setup /shims before pressing new bearings on permantly, you also need dummy bearings).

Changing clutches in stock LS.....whole lot simpler

 

Replacing the discs is a a maintenance task. They do wear, just like the drivetrain clutch wears, that's why the parts are available. When the new parts are in it will work like new.

Hard to be worried about something that's probably going to happen 170,000 miles from now. Buy a Truetrac so the next owner won't have to replace clutches? You're a good man if you do.

 

This is on an 8.8, but it's very similar in procedure.

 

I put the Ford Motorsport Torsen in my 8.8. It's advantage over the stock clutch lsd is that in all the situations where the clutch lsd *causes* the inside tire to lose traction, the torsen will behave like an open diff. It's difficult to stress how much faster my truck is able to get around in an urban setting or 2wd offroading with no drama, no spinning tires, no getting sideways.

 

See i'll probably be the last owner of this truck. It's a towing/offroad work truck in the rust belt and I doubt it'll last another 10 years before it cant pass inspections due to rust...paid 1500 for it, so i'm not worried about the next guy.
