Gidday all,
Quick post before I go out to try and fix my truck (Isuzu Bighorn UBS55)
My Road going bighorn has just had it's power steer / air con belts go loose, then a while later the steering got very heavy at low revs, on closer inspection the power steering pump is really loose and appears to have broken the mounting bolt that holds the power steering bracket to the engine block.
Now this is the 3rd time I've seen this fault on the 2.8ltr 4JB1-T The first couple of times the vehicles arrived to me in that state, with the power steering loose/tied up. I thought someone must of got over enthusiastic and tightened them till breaking point.
So it's pretty obvious this is a factory fault with this model, it must have happened to some of you other guys, how did you solve it? Is there any way to avoid it happening again? Higher Tensile Bolt? What are the specs on the bolt? Thread? Length etc. ?
Thanks in advance
Edit: In my experience this fault requires removal of the radiator etc. and drilling/ EZ outing of the broken off bolt in the engine block.
