I have a 1992 es300 with just under 60,000 miles. I knew there were a couple issues with it when purchasing it recently. I changed both axle assemblies because I saw a small crack in 1 boot and It had a very noticeable clunk when stepping on and off of the accelerator. I grabbed the son-in-law to give me a hand and we changed em up on a sat morning. Well, I never drove the car for a week and the wife hadn't said anything about it, of course she doesn't usually notice much with a car except if it's out of gas. It now clunks worse then before, or just as bad. I'm confused, as I thought that was the obvious fix. Has anyone else had and done the same? and what did you do next? .Oh yah when I purchased them one was a brand new one and one was a re-furbed one. I didn't think anything of it., cause he said it was same as new. Well sure enough if the refurb one didn't swivel the same when putting in the grease etc and I wondered then if it was ok, well sure enough if it sounded like I had rocks scratching inside the axle when we got them done and i knew it had to be that one. We took it out and went and got a new one and then it went in good and sounded fine etc. thx in advance ......

 

Front engine mount is bad and possible (likely at this point) rear mount as well.

 

I just changed my driver's side axle assembly on my 95 es300, as well as the front engine mount and tie rod. i know the wheel bearing needs to be replaced, maybe it could also be your problem. I have a new whole hub assembly coming in today with bearing included.
