Had to do some daily driver repair the other day on Thumper. With 200k miles on it, it was starting to make a very loud thumping at low speeds upon acceleration. After some investigating, I found the drives haft carrier bearing had blown apart and needed replacement. Up on top of the exhaust and heat shield is the drive shaft. With the exhaust removed, and the heat shield out of the way, you can get to the 2 piece drive …

Had this 150k mile X5 come in today with a few issues. The rear tires are wearing very unevenly, and we spotted the upper rear control arms having excessive play in the ball joints, so we will replace those tomorrow. Hard to see, but the upper rear arms are the issue. After pulling the lower pan, I discovered the oil pan was coated in oil. Not often a pan leaks in these cars, so I followed the leak upwards. Turns …

Had this 530i come in for it’s 60k service today. Being an 04, it was time to get the fluids flushed and the filters changed. Step 1: Drain the oil. Step 2: Make big oil mess. Step 3: Drain the coolant and get fresh coolant in. Lifetime coolant? LOL But, we do replace with the proper BMW blue coolant. Then it was time for filters. The air filter here. And two pollen/cabin filters here. Notice the new and the old. …

Finished up the 323i throttle body install the other day. Pretty straight forward going back together, except that we tossed the crappy old torn rubber intake boots in favor of new boots. New throttle body ready to go on. TB installed with new rubber intake boots. Since the car came in on a flat bed, I didn’t really know the condition of the car. Once it was running, it was discovered it had a large oil leak and a significant …

This poor little thing was towed in with an EML light and check engine light on. The EML light typically relates directly to the throttle body being bad (internal TPS sensors on this model), and the CEL revealed a list of about 9 codes ranging from secondary air injection problems to MAF sensors to cam sensors to O2 sensors. Yuck. But, to get it back on the road, the EML was the main issue, so I ordered in the new …

This was a quick in and out project that came by the other day. Car lost all power and wouldn’t take throttle. Turns out the bushing in the gas pedal had rotted out and the cable slipped out of the lever. A new bushing and we were back in business. Driver under panel removed to get at the bushing. Hard to see, but the cable is just kind of flopping around in the hole. And the rotten bushing.

Richard came by today to start the install of a roll cage for his future BMW chump car. With the benders, notchers, and welder out, the guys went right to work. Interior gutted and ready for the cage install. Wes bending steel by hand…….. Ok maybe he had some hydraulic help. The rear main hoop bent to shape and size. From there the diagonal bar was mocked up for the rear hoop and cut to fit. The tubing notcher in …

Knocked out some work on this 330xi the other day. The power steering rack was completely blown out, and since it had been driven dry, the pump was also shot. Nearly 200k miles on the clock, it definitely needs some work. Didn’t get many pictures of the rack R&R as my hands were covered in ATF most of time time, but it involves lowering the subframe down to get access to the rack. Once the subframe is down and suspension …

Knocked this car out tonight. Simple oil change and inspection was due. Mmmm pretty. After removing the oil filter housing, there are 2 o-rings to replace along with the filter. When you pull the filter, you will want to suck out the remaining dirty oil. And to drain the oil, underneath a trap door, is the 17mm oil drain plug. Drain the oil, replace the copper drain ring, and fill with some fresh BMW longlife 5w-30 🙂 Weeeeeeeeee!

Finally got around to putting on the brakes on M the other day. They have been sitting in the basement now for a few months, so with the nice weather, I took the time to get them installed. Up and ready to go. Old brake rotors were pretty lipped. They were starting to show heat spots near the fins, so told me they were pretty thin. The fronts still had a few miles left in them, but not much. Interestingly …
