4WD problem

I have a 99 TRD and when I go to put it in 4wd it shifts in just fine no noise or anything smooth shift it’s once it starts speeding up it’s a big clunk and the truck jerks forward i was told it was a bad diff but not sure could it be my driveshaft or cv axles??

 

only thing i can think of is 2 different gear ratios between the front and rear. no matter what you shift your x-fer case to, the rear is always engaged. so you should accelerate just the same in the front no matter what UNLESS the gear ratios are different. or even possibly different sized tires/wheels.

 

That possibile my truck is supposed to have a 4:10 e locker diff but when I bought it it had a different rear end in it they must’ve tore it up idk but how would I check the gearing on the truck?

 

do you have manual hubs?

No there not manual hubs

 

To check gear ratio as the link I posted shows. You'll need to lock it in 4x4 and trans in neutral and jack up 1 front tire and 1 rear tire(assuming you don't have posi trac) If you do have a rear posi, you'll need to jack up both rear tires. The reason for doing it this way, is the front ADD axle needs to be locked in.

 

I thought I read something on here about the actuator/solenoid thing sticking or something to that effect. Maybe thats the issue?

 

That wouldn't make it bind up.

 

I checked my vin and it’s supposed to be a 4:10 and I checked it this weekend and I have a 4:30 in the rear so I’m guessing that’s the problem

 

sounds like @CodeSeven and @mechanicjon are right. You could either switch the front to 4:30 or revert the rear to 4:10, otherwise your front tires will want to go faster than your rear

finding a locker 4:10 is going to be harder and a little bit more expensive if none are in your area.

 

Yeah I plan to go back to what it had factory which is a 4:10 elocker and so far they are really hard to find

 

also keep in mind it will slightly alter your speedometer. not sure if the PO changed the gear that registers it or not. also depends on the size of your tires

 

I can get you a 4:10 E-locker. Let me confirm price today.

 

Go to the TW S.C. thread and ask around there. Great bunch of guys on that S.C. thread and your right down there anyway.

 

Thanks please let me know

 

I will Thanks bud

 

@ahspurlock is the man to check with, he knows his shit and a real cool dude.

 

He wants $500+ shipping. Shipping could be as high as $85 from Phoenix

 

Is it private seller or like a shop or warehouse sale
