does any body know which possible part went out, compressor, suspension body valve, or height control unit. my friend was driving from the bay area , and his 1998 rover suspension went down, and he cant goany faster than a certain speed.please help.

 

Would need a lot more information to help with this one. It could be one or any number of the above componenents failed.
1st step: check bags for cracks. If they haven't been replaced they are most likely in need of replacement on a '98.

Then get back to us. I don't want to waste time describing every stage again and again for each member so either look through posts or we'll do it step by step. This topic has been covered wayyyy too many times on this forum and many others for me to post a whole walkthrough.

Regards,
