Took the truck in to dealer Saturday for rear shudder while turning at low speeds.They were going to put anti chatter additive in to fix.Went to pick up and they advised about the T.S.B., and are now going to replace clutch.Nice to see that the consumer doesn't allways have to point these things out.Will advise how it works.

 

WhiteNight,

I'll bet you have the limited slip diff., right?

The shudder you feel at slow speeds is a strong clutch and very effective limited slip diff.

I spoke with my mechanic about the same problem. He said that he'd replace it for me, but the fix is putting in a clutch that turns under a lower torque, thus weakening the effectiveness of the limited slip.

I decided against it.

 

Yes.but I am willing to put up with a little more slip.

 

I had my clutch packs replaced, now its nice and smoooooth!

 

Hi folks...

I know we are talking a bit about the rear end shudder... i've got the same.. but as one stated i'll take the shudder for the more firm lock up... but here is my ? it seems my truck has a locking frontend too... on even turf both tires dig and in a tight turn 'dirt' mind you... the truck seems to get into a strong bind/frame twist without slipping the tires... is there a way to learn if the front is in fact a locking front end..??

thanks much

Thats what I'm looking forward to,SMOOTH!!!!

 

Blackbird, you are probably experiencing what most 4X4's do when in 4 wheel drive. The front wheels are turning at a different speed than the rears, and with the differentals locked through the transfer case via the drive shafts you get torque lockup. If you read the owners manual it will talk about driving on dry surfaces in 4X4. You porbably don't have a locking or LS front diff from the factory. Just my 2 cents worth.

 

turn steering wheal hard right put a chalk mark on axial flang. mark other side to. DRIVE PULL OVER AND LOOK IF CHALK MARKS MOVED IN 2 WH .IF SO THEN AXIAL ARE TURNING .SHOOD NOT BE.

 

yes i realize you are right about driving on 'dry surfaces' but when i was working the truck in 4 wheel drive i was in about 1.5 feet of muddy water.... both front wheels where sending rooster tails both in drive and reverse as well as in a turn right or left and even in the wet conditions as you say you can feel the torque begin to stiffen up.. i learned a very hard lesson some years ago with a front dana 30 on a bronco that was an open differential and having it locked up on asphalt... split the carier among other items... ouch.... let me know your thoughts on this if you don't mind.. thanks much...

should i run the truck in 4 wheel drive while the shafts are chalked... thanks again.. Scott

 

Had rear diff clutch replaced today.While driving truck home kept expecting the shudder to reappear, but it's gone.Totally different truck.
