94 Previa All-Trac questions
Hello, I'm a new owner to a 94 previa All-Trac auto. I have some questions.
It's throwing an EGR code. Is the EGR pretty easy to replace? Can I just pull the current EGR and clean it out, or do I need a new one?
The Previa seems to slow way down when I'm pulling into parking spots. I think it might have to do with the front differential. Is it getting ready to go out? It doesn't make any sounds, unless what I hear when driving around (a hum that sounds like mudder tires) is a hint to a front diff that could be on its way out.
Can I unhook the front drive-line and just run RWD? It almost sounds like (what I've read) having an all-trac is sometimes more hassle than it's worth. If I could just unhook the front drive-line and run the rear wheels without having any issues, that would be great. I don't think there are many Previa's around my neck of the woods in salvage yards.
Also, I'm looking at lowering my Previa. Has anybody tried the RSR springs? I saw them online. They offer a 2" drop. I was thinking about ordering them next week. I don't want to go the bagged route, and I don't want to buy JDM stuff. It's too pricey for my budget.
Thanks in advance for your input.

Hmmmm, no responses at all? Bummer deal.

Though I've owned an AllTrac Previa before, I am not 100% familiar with how the center diff functions.
If it's like my Torsen-based Audi Quattro, disconnecting the front driveshaft will make the rear wheels do nothing.
If it's like a Vanagon with a viscous coupling, you can remove the front driveshaft and drive the bus as rwd.

If i remember correctly, it's a viscous coupling. I think i read that somewhere.

Hi Leppah,
Check out this post on ToyotaVanTech: http://www.toyotavantech.com/forum/s...vations-(long)
It mentions the fact that the All-tracs have a viscous coupling...so hopefully that answers part of your question.
In terms of lowering your Previa stuff...I noticed that you've already discovered the Previa Springs thread (http://www.toyotavantech.com/forum/s...-springs/page2 ), so you probably have a good start on that.
For the EGR stuff, have you been able to read this thread: http://www.toyotavantech.com/forum/s...aning-write-up
or this one http://www.toyotavantech.com/forum/s...ith-EGR-System
Hope this helps!
