After some mud-playing, my steering pum makes a "buzzing" noise. I searched the forum, but I couldn't find a relevant answer.
After the mud playing (a very sticky mud, of at least 30 cm deep) I washed all the underside of my 2000 TJ, hoping that this was beecause of the clogged joints etc. I checked the level of the steering fluid, and I added a little bit (it was between the low and the full sign). This didn't help, either. The noise appears when steering in place or at slow turns. Also, it seems that the steering is hardder, when buzzing. It is the same noise that I could hear before, when the wheels were sttered at maximum turn. I checked the belt and seems to be OK. Anyway, visually, I could see any slipping of the belt when steering on place. What could it be? Should I start thinking of changing the steering pump (I hope not - I just bought the car and I already have a lot of things to change - oils, filters, some U-joints, some oil gaskets - on the front and rear axles, brake pads etc, and my budget is really tight). Or I might solve it cheaper?
Many thanks, in advance.
