Yes, but you need the Bosch *784 injectors for your year

Default Hack n tap SYE and still vibrates

I installed the Iron Rock Offroad hack n tap sye and it vibrates worse now than it did before. At 55 mph it seems like it is going to blow up.
What else can i do? The instructions told me to take my 1 inch tc drop out so i did.

what's you setup? Do you have a double-cardan/CV driveshaft after the sye?

You need to set your rear pinion angle so that the input shaft of the rear axle is parallel to the driveshaft.

Yes, i put my front shaft in the rear. I was trying to NOT do shimes or a tc drop. I guess i still have to what they say i didnt have to do, thats why i got the sye.

just to be clear, you do NOT want the TC drop with a SYE kit. That part is correct.

You do need to shim the axle to bring the pinion into line with the driveshaft though. I recommend 1-2 degrees below parallel to account for axle warp under acceleration

OK, thank you, i wil put a shime in the rear. I'll see if Iron Rock offraod can set me up since they are 7 miles away and they are all cool people.

in an emergency / very short term situation, it's acceptable, but will cause very heavy wear on the u-joints, axles, tires, and especially transfer case when driving on dry pavement in 4x4. You don't want to run like this for very long due to the risk of damaging components....

Ok I'm very concerned about this. For the last month or two my front drivers wheel has been making a loud humming noise, especially when I'm between 30-45 MPH. I don't know what it is it could be coming from the wheel, axle, I'm not sure. But I believe it is only on the front drivers side. Any ideas? It seems to drive just fine.

humming usually indicates wheel bearings are going bad
