Strut Mount Number

[99lexus]

Hi,

I am looking for two OEM front strut mounts for 99 ES300. I ask two different shops and they both gave me the different part numbers.

One shop gave me : 48603 33010 and 48603 33021.

The other shop gave me 48609 33121 and 48603 33021

Do you know what is the redesigned strut mount part numbers?

Thank you.

I just bought these parts from Park Place Texas as i need to do the replacement on my 99 ES as well.

This is what I have:

48603-33021 & 48609-33121 is the left & right strut mount. Don't know which # is right and which is left.

A little research showed that 48603-33010 is superceded by 48603-33021.

I also ordered

48471-41010. This is called the seat where the upper spring insulator mates to. This part is the same for left and right sides.

90903-63014. This is the bearing that goes between the strut mount and seat. This part is the same for left and right sides also.

I chose to reuse the dust boots & bump stops tho.

I figure since I'm taking the suspension things apart, I might as well put back new stuff back in. I plan to do the work this Sunday.

Whoa.... I thought that when replacing the strut mounts that the bearing was inside the mounts? I didn't realize that the bearing had a seperate part number.

So when I order everything, I need to order four bearings as well as four mounts? If this is true then I am glad that I saw this thread before I ordered them this week.

I plan on ordering bumpstops and maybe the isolators/seats as well, and I understand where they go and why. I also understand why the strut needs a bearing to rotate on, but I thought that it was inside the mount.

More parts I have to order = :chairshot:

Yeah, bearing is separate. I didn't do my rear sets so I'm not sure if it's the same situation (most likely). Check the schematics just to be sure and double check when ordering that the front bearings are the same as the rear. Rear mounts & seats will be different of course.

My 99 has about 49k miles, and found the front dust boots & bump stop to be ok, so I didn't order new sets. If you have higher miles, probably safe to order new dust boots/bump stops. My bottom spring insulators were bad though. I recommend you add the bottom insulators to your list. I didn't and so had to improvised. I did the change just this past Sunday and the dealer was closed so had to improvise....needed the car up and running Monday. I bought 1/2in dia heater hose, cut it about 1.5 feet length, then cut it open and wraped the bottom coil. I'll be keeping my eye out on them just in case.

Edit: Out of curiosity I checked the rear suspension components and there doesn't appear to require the bearing like the fronts. Confirm with the place you are ordering from.

Thanks.

It makes sense that the back wouldn't need a bearing and the front would.
