When i go on trips that are 50 miles or more and make a sharp turn or any 90 degree turn. My truck seems to make a wicked noise and leaves rubber on the road! It vibrates my whole truck my mirrors shake and everything! I was told i have a postive rear but i'm not sure! Than the trans issue! It has a billet convertor, and shift kit in it. When the truck shifts at 5 mph it gives me a really good kick and when it shifts at 15 it really gives me a good pow. Is this normal or do you think the valve body it going? The truck has 200,000 miles on it..I'm kinda new to diesels and want to make sure i have no serious problems or any thing.

Thanks guys

 

your lsd might be going out and staying locked up.. have you serviced it ever? on the trans have you had the tv cable adjusted? that makes a huge difference yours may be off or tight as mine was off after changing the apps I didn't clip it on all the way and when I backed off the throttle is shifted really hard

 

I have never serviced it ever.. I just got the truck a no more than 2 months ago. What is the lsd?? I have also never had the tv cable adjusted. I do know the apps was changed recently though.

 

Limited Slip Differential... Its a Posi-Trac in other words... Go to Napa and get some Friction Modifier, put a whole bottle int he rear diff and drive around. It'll free up.

 

Ok thanks for the info i will do that as soon as i get home!!
