Rear differential bushing question

I need to replace my rear diff bushing. This is a 99 328i. Can anyone give me the correct part number?
On pelican parts, I found a

33-17-6-751-808-M69

Differential Mount, Rear, BMW E46 3 Series, All Except M3 (1999-05), Each
Brand: Lemfoerder

On Real Oem:

RUBBER MOUNTING REAR 2 33316770781 $26.23

Which one is the right one? Do I need both?

check with realoem.com.

They'll have the exploded parts diagram, you can pull the part number from there.

I've not heard too many good things about Lemforder.

Once you get the part number, you might want to check with Ruben at Desert Motorworks to see if he could order the Meyle HD version for you.

I just need to know if they are the same part - bushing and mount...Real oem has it as RUBBER MOUNTING REAR

DesertMotorWorks: how much for the Meyle HD version for a 1999 328i? Thanks

There are actually 7 bushings back there... 6 of them are for the differential/rear axle carrier assembly, and 1 connects to a tab on the backside of the differential itself.

The bushing you found on pelican parts is the bushing that attaches to the backside of the differential.

The number that you quoted from realoem is for the TWO rear-most carrier bushings.

If you look at the drawing you'll see:

a bushing identified as "7" on the drawing... there are two of these, they are called rubber mounting front.

a bushing identified as "2" on the drawing... there are two of these, they are the rubber mounting front.

a bushing identified as "4" on the drawing... there are two of these, they are the rubber mounting rear. (carrier)

and one bushing identified as "9" on the drawing... this is also called the rubber mounting rear, but it is directly attached to the differential, while the other pairs attach to the carrier assembly.

As you can see, BMW uses similar descriptions for the bushings, so you need to figure out which bushing or bushings you want.

I know that Meyle makes an HD version of bushing "9", and I'm sure Ruben could help you with that item.

Does anyone know which bushing normally needs to be replaced when there is a "thud" noise when letting go of the gas or depressing the clutch?
Or will i have to purchase a set of jackstands and go under my car and have a look? Someone has to have done this before and I think normally its one bushing that fails.

You most likely need "bushing no. 9" on the realoem diagram, BMW pn# 33176751808.

I would recommend getting Meyle pn# 300 331 7601/HD instead. It's a heavier duty replacement for the OEM part.

No problem. It would still be a good idea to get under the car and see what really needs to be replaced before buying any parts. Shouldn't cost you anything to have your installer put it up on a lift to inspect the bushings and give you an estimate on the needed repairs.

Is this a DIY installation? Has anyone here replaced this bushing themselves? I need to replace mine soon. I haven't checked the service manual yet, but wondering if anyone had any experience.

You can DIY but it's a real PIA. I do almost everything on my car but was more than happy to pay someone else to do the diff bushings for me.

There are no bushings that attach to the diff unit itself on the E46 (E30, E36 yes). The rear bushing is pressed into the diff carrier. A large bolt goes through it and to the diff cover. It's a pita to replace because you have to drop the diff and press it out/in. rear bushing part number #33176751808.

^as he stated above. There are 7 bushings in the diff carrier/subframe.
But three of these are used to connect/buffer the diff unit to the carrier(the other four connect the carrier/subframe to the rear floorpan). Of the three used for the differential, the single rear one is often the one that goes out. You can probably crawl under the car and look with a flashlight to view the rear bushing's quality. The other two of the differential connect the front of the diff to the front of the carrier. Those don't go out often, and are hard to view with the diff mounted. Several aftermarket kits have the three diff mounting bushings in the kit. Some are solid and semi-solid. If Ruben from DMW has a HD version of the rear alone, that might be the way to go.

So Ruben, do you guys have a Heavy Duty rear diff bushing for the E46? Any pictures of what's improved/reinforced? Very interested. PM me a price if you can.

Yeah, I do all me work myself also... Its hard to see paying someone to replace a part thats sitting right in front of my face. Did you get it done at the dealer? How much was the labor charge?

If you are a frequent DIYer and have the proper tool to extract & install the diff bushings it isnt that bad. You NEED either the BMW special tool, the one from bimmertools.com, or a homemade version. There is a very good DIY on here, read it several times beforehand. It may be a good idea to pick up replacement torx bolt which mount the drive axles to the diff flanges since they are torqued to about 70 ' lbs and tricky to get off w/out a little rounding. Best of luck and DIY!

FYI: The labor rate for the rear only is ~3.5 hours according to alldata but I got quoted something like $750 from dan martins' in gaithersburg. I ended doing it in 5 hours w/a frame lift, hand tools and a homemade press tool. I'm about to purchase to proper tool from bimmertools.com and for a very small fee you can use it if you like. DIY!

too bad you don't live in tx, or i'd give you my diff bushing removal tool. its not really a super easy job, but its not super complicated either. you have to remove your rear diff, which you'll need a E12 torx socket to do, as well as a 21mm wrench and socket, a 18mm socket, a 13mm socket(for removing the crossmember thats in front of the rear diff), and the bushing removal tool.

http://forum.e46fanatics.com/showthread.php?t=527354

this thread links to the diff bushing installation/removal tool, but i modified mine, hence posting that thread. although i doubt its necissary to go with the thicker threaded rod for regular bushings, i did for my aluminum ones.

Where is that very good DIY??? Searched but could not find....

And why are you buying the tool now if you've already done yours? I may be interested in renting it.

I'm about to order the Meyle HD bushing from Reuben - which one did you use?

Dealer? Uh, heck no. Went to a local indy. IIRC, was about $300 for all 3 bushings. When I was getting quotes, most shops were quoting $550-$600 with a high quote of $900 (I think that shop either didn't want the work or was scared of what they were getting in to).

It doesn't really look any different on the outside. Presumably it's just made from better rubber (may also be reinforced somehow internally, not sure).
