i was on the freeway yesterday going about 80 and when i took my foot off the gas my truck made this horrible grinding noise and started shaking pretty harshly. this happened 6-7 times and only seems to happen when im going that fast. im thinkin it has something to do with the lift that i just had put on, b/c this never happend before.

Are you running the stock gears or 4.11's? IF 4.11's, it sounds like the governor is kicking in(at maybe 80-85?). That's normally when you re-gear, at least to my knowledge.

I would first stab aguess at the driveshafts/joints. Vibrations after a lift are common in those if they need replacing after a lift on Discos.

The least expensive fix to this problem is going 75 :grin :grin

James,
How much lift? What Mfg? I did an OME 764-f 781-r and had to replace both driveshafts. I agree with Chris u-joints/driveshaft. The front went first with very a similar reaction to what you are describing.

James check out Tom Woods driveshafts. I put two of his double cardan shafts on my 90. I think the web site is www.4xshaft.com.
A really great product and a really good guy. Best of luck.

and I thought going 65 was a task :eek:
Heck, I regularly get mine up to 90 on I-25.

Matter of fact, it does real good at speed on the open prairie as well. :grin Was hunting antelope last weekend and in order to herd them, you gotta outrun them.....
