I have a 1993 Isuzu Trooper LS with a 6 cylinder. Does anyone know
where I can find a diagram for the vacuum system. I'm not sure the

once it gets warmed up and I'm headed slightly uphill. Backing off the

UK 1998 Isuzu.
Has had a rattle from nearside fron wheel area for many months particularly
when going round a long right hand bend, been unable to find anything, no
apparent play in steering, drive shaft or suspension, little bit in wheel
