RX300 front suspension deflating both sides.

Recommended Posts

My front suspension deflates overnight on both sides evenly and then pumps up when I start the car in the morning. The rear retains the air OK. During driving I occasionally hear the compressor kick in so I am guessing there is an air leak somewhere, but where? As the front deflates evenly it would not suggest the struts themselves. Any ideas?

Put some water in a spray bottle and add Fairy Liquid or other washing-up liquid then spray (or brush if you haven't got a spray bottle) the soapy water over all pipes, joints, struts etc.

Where you see bubbles form, there be your air leak :thumbsup:

Struts fail individually in my experience...

Any progress?

Had it into Lexus the other day for assessment but all they could come up with was to replace both front struts with no guarantee of solving the problem. I don't think they tried very hard to find the leak so will try the spray liquid on all the pipes.

Would be useful for have a pipe layout plan if anybody has got such a thing.
