Strange sound when leaving a stop

Hi guys and TW gurus,

Firts i hope to use the good words so you can clearly understand what i'm trying to describe.

When leaving a stop and normaly accelerating (gently, absolutly not enough to spin the wheels), not changing direction, i'm earing the rear driver tire screeching. It's only for a 1/4 second. I can't say if the wheel is spinning or braking. It's easy to duplicate it when pavement is wet but more difficult when pavement is dry.

It's abit like the rear wheels were not synchronized for a short moment.

What do you think about that?

 

I see you have a nice lift package . Just wondering how often you use your e-brake and if you have extended brake cables ?
Hows the gear oil in the diff

 

The parking at my house is in slope so i'm using my e-brake every day. I've used frequently the e-brake on all my vehicules in the past.

Brake hoses have been extended front and rear but not the cables for the e-brake. I've relocalised the bracket taking care to not strech the cable. I'm running this setup for a while now and never had the problem described before.

I'm suspecting a rear differential problem but asking here cause my knowledge about differential is limited to basics.

 

OK bump.

Willingt to hear feedback about the behavior describe in the first post. Can a faulty torque converter can produce this kind of problem? Torque coming too fast at low acceleration? A faulty bypass valve in the SC?

I have an other potential symptom that is maybe related. I'm supercharged and i have a boost gauge. Since few weeks know, the boost seems to hapen lot earlier at low TPS openning and low rpm. At low speed if i give him a bit of throttle it can raise to 2.5-3 psi even at 1800-2000 rpm. It seems to be related to engine load and transmission shift. Except that, everything is normal. Same vacuum at a stop and same max boost at WOT.

Last week, when leaving a stop, the truck almost stall! The stop later, it has stalled. Restart it and everything was ok. Never happened again since.
