How do I decipher my VIN #?

I need help deciphering my VIN #. I have a 2001 wrangler Sahara 4.0L w/ 5speed. I think It has a D30 front and d35 rear due to the rubber plug in the rear. I am trying to fing the correct parts for new ring and pinion gears to use 4.10s. any help would be appreciated!!!

Yes the front is a D30 and D35 rear with the rubber fill plug.

Are you wanting brands and a parts list to get the gears change to 4.10's?

Your Vin # wont give you that. If your looking to know what gear you have now just look on the rear diff cover there is a tag on the left side of the cover the gear ratio will be stamped on the tag.



If you still wish , post your vin # and I'll decipher it for you.
You can also get the factory build sheet from jeep.

distortedtj,

Yes I am looking for brands and trying to decide if I need to change axles to accomodate the new gears or just leave it as is. I go off road frequently but no extreme crawling. Again, Thanks!

No problem give me a little bit to do it.

For the factory build sheet you can go to a local Dodge/Chrysler/Jeep dealer, go to the parts or maintance desk and give them your vin # and ask for a build sheet print off.

You can also E-mail jeep and just ask for it and they will e-mail it to you.

4.10 is a good ratio for that combo.

As for brands that a personal choice. I like Yukon Gears.

You'll need ...

ring and pinion sets...both front and rear.
Master install kits to include all bearing and seals
fluid of your brand choice.
and a PROFESSIONAL installer.

Gear set up is not something to be done by the average do it yourselfer.
YOU MUST DO BOTH AXLES if you want to use 4wd ever!!!

Alot of shops/installers will not warranty parts not purchased through them.
My suggestion is you check around your local shops for a shop you trust for prices. They can help you with all the parts you'll need.
Average price for front and rear gear install...$800 to $1600.


Any more questions let us know.

You would be better off trying to find a set of complete axles from a 4 cyclinder. They are 4.10 stock. Normally a lot cheaper to do this then swap gears. Here is a jeep yard that is local to you www.webejeeping.com
