Nope, you can wiggle your hand in there, I did it last month. It was an easy, fast job, replacing all the rubber hoses without removing any of that. Now if you were doing the hard high pressure lines I'd say remove some things. No mistakes can be made, the hoses are both different sizes.To do the return hose (reservoir to bottom of pump) you need to pull the fan, belt, ac compressor, ace pump, idler pulley. This is just to get the pump and bracket off so you can get the the hose clamp on the bottom of the pump.
You will need to order a hose.
My LR2 has developed a loud whinning noise with jerking of the steering wheel while driving. Teh PS fluid is circulating. I had the system flushed without success. Im replacing the PS pump now. Is there a way to find out if there is a in line filter that might be blocked? Ive traced all the hoses and not found a filter so far. Also is there a was to flush the hoses to make sure there is no blockage of any kind?
