Could be warped rotors.... check your owners manual, but my 2003 calls for 150-165 lbs for all lug nuts. If a tourque wrench was not used, and either an impact wrench, hand or those "tourqe sticks" that go on an air gun... maybe to blame???
Warping rotors and "pulsating" have been frequent topics for 2 - 3 years on this site. May take to Midas or dealer and get a "free check" and see what they say without you saying anything... just so you can compare.
Maybe something else, but this is a first place to start.
Let us know.

I put the rotors on they are sloted and frozze. They have been fine, but thats what I thought it was, I put brand new rotors on today and as I pulled out of the driveway I had the same pulsating right away.

I had the same problem with a new set of performance friction rotors on my 2000 Excursion. I thought I had did something wrong intially however I found out the rotors were warped from the get go. Carolina clutch replaced them. The moral of the story is sometimes they come that way from the factory. I wish I can say the performance friction rotors solved my problem. They lasted around 40,000 miles before warping.

I just did the rotors and pads on my '01 last night. I used all Bendix parts. Took it for a ride around the block and all was good. This morning while at hiway speeds I noticed some pulsation (I was pissed at first). It was raining, and I suspect what was happening was the new pads/rotors were not seated/broke in yet. The more I used the brakes the less the pulsation was. I read right on the Bendix box that it takes ~100 miles for the new pads to "break in". I am going to wait until a dry day before I fault any of the new hardware I installed.

Its also a good idea to do some heat cycles for these harder pads/slotted rotors when you first get them on. Also try to hold the brake pedal down as little as possible when coming off a long off ramp. Nothing spells warped rotors like an extremely hot caliper clamping down on the disk at one point for an extended period of time.

New rotors are not necessarily trued. Some shops will actually take new rotors and true them up on the lathe first.

I am having the same issue currently. I just replaced all my tie rods too. The truck was not having any issues until I replaced them too. I noticed that the drivers side inner tie rod was frozed solid as well. I am going to remove the rotors and have them checked and trued.
