wits end re: steering whine.
got the steering whine problem, and i need some advice.
sometime towards the end of last year, i started getting steering whine. thinking it best to change the reservoir, i ordered a new one and 2 litres of tutela green fluid.
changed it myself and that sort of worked for a little bit but not really. was losing fluid so the whine would come back.
anyway, recently its been getting worse. thinking it might be the rack and/or pump, i took it to autolusso for a saturday surgery check up, but they couldnt find a source of the leak.
with a new rack and pump, i was looking at a quote of £1200.
the other day, i drained the fluid in the res, and dumped a bottle of lucas stop leak in there.
started the engine with the cap off, and after a few mins of idling, the fluid in the res began to bubble, froth and overflow.
turned off the engine, started it back up, and it was perfect for 2 days.
now its back.
so what im curious about is what could be causing it.
now i know where the fluid is going (out the top of the res), im thinking it might be possibly the res is faulty even though its relatively new.
i never topped up the old res when it started to whine, i simply swapped it out as a preventative measure. the old res was most likely fine as it was, just the fluid a little low.
could a faulty rack or pump cause the frothing and overflowing of fluid?
