    Re: Caravan PTU info

    Thanks for sharing that! I was always curious how much grinding had to be done. That honestly doesn't scare me all that bad. I am really curious about the 2.2/2.5 block. If the weather stays clear...

    OOHHH!!! Driver's side! I thought that was the same size for some reason. That makes more sense! Duh!

    Re: Caravan PTU info

    OK, so Friday afternoon I went and re-read a bunch of the AWD threads. Carlos bored out the bearing retainer, but I think that's because he used a 5-speed one instead of the AWD one for some reason....

    Re: Caravan PTU info

    I believe the 41TE is taller due to a thicker FD ring gear. It's been a while since I've read up on this. There was a thread about adapting the OBX to the 413 a long time ago.

    I honestly don't...

    Re: Caravan PTU info

    The only difference between the regular diff and the AWD diff is that the case on the right side has the drive splines for the PTU and the larger bearing/seal surfaces. I have looked at it over and...

    Re: Caravan PTU info

    I wonder if he'd be willing to make just the case part for existing OBX/Quaife/Peloquin/TU units for AWD use? I inquired about this when TU was doing their run, but it wasn't in the cards.

    Re: Caravan PTU info

    That may be true. I think there is more clearance for the 2.4.

    Re: Caravan PTU info

    Because of the position of the ring gear being on the input shaft, the case protrudes past the adapter plate/bearing carrier of the transmission. This causes interference with the oil pan rail on the...

    Re: Caravan PTU info

    For what reasons? Just curious. I know there's certain aspects to it that are desirable, but that case interference thing is very close to a deal-breaker.

    An interesting note is that years ago I...

    I will see if I can get them to post up. It's one of the reasons I just emailed them to Vigo. I just noticed my subscription ran out, too...gotta renew!

    Re: Caravan PTU info

    The Pacifica PTU is a different design and places the output shaft above the centerline of the FD diff in the transmission. The van PTU places the output shaft lower than the centerline of the FD...

    Re: Caravan PTU info

    The reason for the different gear ratios front to back is due to the VC. In order to ensure that the VC will act as quickly as possible, it must always be in a slight state of slip (a few %). The...

    Re: Caravan PTU info

    Following. I got those pictures for you. ;) I am also curious on this as the Pacifica PTU raises the driveshaft output up quite a bit while the van one seems to lower it. I like the design of the...
