Rear brake odd issues

[cstishenko]

2007 Ranger FX4 Level 2

So for the last year, i've had a "hopping" vibration @ 70km/h +/-

It seemed to happen ever since I put 2" bolt on wheel spacers on the truck.

It started happening when I was on 31" Goodyear Duratrac tires, i'm now on 33's of the same tire... And it is only more pronounced.

It feels like the rear end of the truck is hopping.

Now i've tried taking the spacers off, i've tried rotating my tires to see if the hopping goes away. Nothing.

One thing I also did was drive along and slowly press on the e-brake.. the hopping became more pronounced again. Now one time in my underground parking i pressed the e-brake too much and ONE rear wheel skidded.

Do I have a rear brake/ drum issue?

so, i have a feeling it might be my spacers.

A friend of mine who has the same truck, same setup.. Recently put spacers behind his stock wheels and is having the same issue.

If his is cured by new wheels, thats the way I am going too.

Sounds like the spacers where preventing the wheels from centering in relation to the axle. Your tires could be out of round or may just need to be balanced. Have you inspected the inside of the wheels for foreign material, like mud or dirt buildup?
