Front-End Hops
When I'm braking between 32-37 mph the the front end hops up-and-down, then resolves when speed is down below 32 mph. It does not hop when braking above 40 mph. What could be causing this? My truck is a 1988 F-150 4x4 302/AOD.
Any help appreciated.

I had a similiar problem with a '78 Bronco... I found that the factory shocks couldn't handle the 33x12.50 tires. After replacing them with a quality shock (Gabriel Adjustable "E"'s at the time), the problem vanished. I was using Rancho 9000's on my '94 crew cab before I sold it...loved 'em!

Rob ,
Warped rotors will cause the hop you described ..Do you run bigger than stock tires ? I find Ford trucks can be fussy with tire pressure in larger tires causing the braking hop if the pressure is lower . It can be a combination of all the things mentioned in the above posts as well . Start with increasing the tire pressure a little , maybe have the rotors resurfaced and have a look at some new shocks . These new Monroe Reflex shocks seem to be a quality product but they are kinda pricey .
