Lotus Elan

rear drive shaft seal

PostPost by: Hongokongo » Wed Apr 02, 2014 5:48 pm

I have an oil leak where the drive shaft comes out of the diff. case, even though it was rebuilt in recent years, and little used since then.(Which may be the cause) However, I have bought a new seal, but the garage that is going to fix it has not done one before, and has asked me to ensure that I don't need any other part other than the seal. Is there anything else I should get. Looking at the Parts list there is nothing else. It's an Elan +2.

I'm sorry, I would tend to turn the question around on its head and be asking where the nearest reputable mechanic is who has done one on an Elan before :D

If you're sure the bearings are OK (both sides) then maybe just a new circlip in case the old one gets damaged coming out.

Tell your mechanic to use a slide-hammer if possible and/or not to place the puller on the delicate aluminium ring around the output shaft.

I suppose it's possible to do the job with the diff in the car. If it does have to come out then I would think about replacing both seals and both bearings - they're not expensive.

Don't forget a good diff oil. Smear the inside of the seal with some.

it's easy to remove driveshaft with the diff still in car. NB make sure after you remove the circlip that there are no burrs or damage and it is perfectly clean BEFORE using sliding hammer. The sliding hammer is attached to the driveshaft doughnut holes with NO contact with the alloy diff casing. Maybe you will need to make an adapter plate to attach sliding hammer to doughnut holes. IMHO you need to change the bearing at the same time, this is very cheap and the same as the narrow bearing in the hub. While the driveshaft is out check that the doughnut bolts are a good sliding fit in holes and not worn. They can become worn and cause a clicking noise when driving car. Also when assembling be carefull not to damage lipseal when sliding in the driveshaft on assembly
Gently does it with the sliding hammer
