Problems On Avensis 03 > Manual Available?

[CaptGutter]

I currently have a number of problems with my 03 Avensis (current shape).

Firstly, my turbo is not kicking in so my accelleration is almost non-existent.

Secondly, from the drivers side front end I get a noise that sound like I am driving over rumble strips, that increase and decrease with speed.

Thirdly, I get a heavy knock when I drive over a bump/pophole/speedhump.

Fourthly, the speaker in front of the driver can no longer handle any volume.

Before I take it in anywhere I would like to get an idea what the problems are and whether I can fix them myself. Ideally I would like to get a manual.

Anyone else encountered any of these issues, and if so what way their cause?

Turbo problem? Lot's of reasons for this, from induction pipe collapsing to duff Turbo. One for Toyota or friend with code reader.

Noise from front, possible wheel bearing rumble?

Knocks & bangs, could be Anti/Roll/Bar links & bushes?

Best to jack up vehicle & look for any play in front suspension/steering components, ball joints etc etc.

Bad roads kill A/R/Bar links & bushes.

Swap fornt Speakers over & see if you have a change in quality.

I am guaranteed to change a set of links Front or Back every year without fail. Good quality links, but crap roads.

I think w/shop manuals available via computer disc?
