Here's a video of the issue that has been around since the swap...




Please advise!

Weird, the only time I've seen that was with a welded center diff or broken one, something is binding in the trans or rear... This is a question for Jerry.

I don't see a video but it may be cause I'm viewing from my phone.
Is the tranny, t-case and rear the ones that came with the car from the factory?

[wishiwasfast]

Yep, they are. They are all matching condition.

That acting like the center diff or the rear diff has been welded. Or worse something is binding them up. Id start by pulling the rear diff off and looking there upload some pics, then if there isnt anything wrong drop the trans and pull it apart and go from there. Who did you buy the swap from?

[wishiwasfast]

From Jerry, whole swap.

cant really tell from video. does car drive like the brakes are stuck on? may be hard to tell with auto

[wishiwasfast]

AnyOne want to drive it?

[wishiwasfast]

To an extent it feels like it.

Is this swap from the auto car that Jerry parted out? If so please tell me this car is auto.... If not then yea you obviously have a problem. You need to change the ring and pinion in the rear diff.

I live in Palm Harbor by Alderman rd and US19, I will pm you my number,hit me up.

sounds to me like your center diff self welded itself. not uncommon. especially if you drove car with space saver.

symptoms would be drivetrain chatter as front wheels move faster that rear when you turn. will feel like brakes are on during coasting. the bigger difference between tire sizes front to rear the bigger the brakes. even brand new tires would be different sizes after just 200 miles. went through these pains with welded diff in yellow car years ago. this is why I dont recommend welded center for street cars.

It was like this before the blow out. It was like this the first time we drove it out of the driveway. The rear tires are wearing very quick. so I have a new trans, etc lined up.

if tranny is otherwise working well i wouldnt risk replacing it. the center diff can be removed in the car.

in a FWD car when you turn the outside wheel has to travel a greater distance. thats what the differential is there for. to allow the inside tire to turn slower and the outer faster. when the diff is welded its a nightmare to make a u turn. the inside tire has to turn backwards while the outer turns faster. very hard on the tires. they literally scrub to death during turns.

the front and back wheels of AWD car act like the left and right wheel of FWD. and the center diff is like the diff in FWD. when front tires are turning faster the rear have to go faster than the pavement to catch up. so they are screeching across the pavement. this is very hard on the drivetrain. especially rear diff which will chatter and heat up quickly.

the car had a what sounded like a dragging rear rotor from sticking break caliper or possible a worn bearing. both of which would have masked any other sound the car may have been making. hope you get it worked out with too much pain..

[wishiwasfast]

The rear bearings are new, OEM. The rear calipers/pads/rotors are new also. Its definitely drivetrain. I'm going to replace everything then look at all the original parts to see what failed.

can you drive it here??
