Brake and wheel bearing upgrade

[jaggermouth]

Would one recommend putting later 1999-2004 wheel bearings and brake rotors on or will the e99 hold up with a 4" lift and 38"-40" tires? I currently have 35's on my stock height with no problems yet.
Thanks

The rotors and wheel berrings are basicly the same, only spaced diffrently from early to late... I have both types, compaired them side to side, and did in fact swap my early '99 wheelberings and rotors to the newer style late '99/2000. You must change both the rotor and the wheel berring, the offset in the berring is counteracted by the same oppiset offset in the rotor... caliper never knows the diffrence from one to the other, caliper seems to be the same. There is only about 1/4" diffrence, but the newer style will make the front tires sit about 1/4" farther out of the fenders.

My only reason was having warrenteed parts on hand for the newer ones, and a set of freshly turned newer rotors...

Rotors, side by side...


Hubs, side by side...


However, in your case, running bigger tires (38" plus) I'd recomend the kits that convert from the unit berring style to fixed spindle and tappered berrings with adjusting nuts like a Dana 60 from the early 80's would have. Mutch stronger design, and worth the money. If you are willing to spend $3000 on fancy aluminum rims and new rubber in the 40" range, the $1800 for the spindle kit will be worth it over the life of the truck. Good luck eather way...

I had these on my 99, never did wheel bearings again. Kinda pricey though.

I converted my truck to late99-03 bearings and rotors a few years ago for ease of getting parts. It was actually cheaper to get new bearings and rotors for late99-03 than it was to get bearings only for the early99.

What about for the 2wd e99s? I'm about to do bearings and rotors on my 2wd and would like to swap to the newer style. Is it basically the same thing and easy to swap or are the 2wds different?

[dieselcrawler]

I think the 2wd's are diffrent... the rotor and hub are one pc, and the berrings are a tappered berring with adjustable lock nut, not the non-adjustable unit berrings like in the 4x4 trucks... Not sure of the break diffrences there... I only have 4x4 trucks.

So I just change over the bearing assembly and rotors to the late 99 style? And what diameter of rotor do I need for the front on a F350 SRW? Oh, I also have Warn manual hub lockers, so would I be able to retain those in the swap?

[dieselcrawler]

match up the sizes on the rotor you remove... and yes, the lock out hubs you have will work on the replacement unit berring just the same...

Not to hijack, but are there any upgrade rotors for the E99s? My brakes are about 16K old and I have warped the FoMoCo rotors twice and they are expensive to have turned.

Instead of buying a set of late model rotors, has anyone just used a washer on the caliper mounting bolts to get the correct spacing?
